Chapter 1602: A lens worth 1 million yuan

On the screen, a green dotted line representing the stabilization effect (positive value) is superimposed next to the blue curve representing the original lateral net stability derivative.

Next, a new red curve representing the comprehensive net stability derivative is calculated and overlaid on the original blue curve.

Three pairs of eyes were fixed on the key area near Ma=1.03.

I saw that the blue trough, which had originally plunged deeply into the negative area, was significantly lifted up under the strong "support" of the green stabilization curve.

Although the red curve still has an obvious depression at Ma=1.03, its lowest point has firmly remained above the zero point (X-axis) of the coordinate system!

Although it is still lower than the ideal value, it has left the dangerous negative stability area.

"It's straight! It's straight!" Yin Kaixian pointed to the raised valley bottom. "Although the margin is not large, at least in theoretical calculations, the net stable derivative is already a positive value..."

The derivative is positive, indicating that the static instability of the aircraft will not drop suddenly.

It is a relatively safe result after all.

Xing Muchun patted Yin Kaixian's shoulder vigorously, with a relieved smile on his face:

"Good! Great!"

Chang Haonan stared at the red curve, and the corners of his tense mouth finally relaxed slowly.

He breathed a long sigh of relief, as if a heavy burden had been lifted from his shoulders.

"Okay." His voice was steady, but with unquestionable affirmation, "This shows that the overall design concept of the 'Zou Yu' prototype is valid, and the key risk points have been dealt with. The subsequent detailed design and test flight will follow this direction..."

"..."

At this moment, the encrypted phone in Chang Haonan's pocket made a unique beeping vibration.

He took out his cell phone, looked at the number, his expression slightly moved, and immediately answered the call.

"It's me." He only listened for a few seconds and his eyes suddenly became sharp.

The relaxed look on his face was instantly replaced by an urgency mixed with surprise.

"Okay! I got it! I'll be right back!"

He hung up the phone decisively.

"Mr. Chang?" Xing Muchun and Yin Kaixian both noticed his sudden change of mood.

"There's an emergency in Beijing, I have to go back immediately." Chang Haonan only gave a simple explanation, then turned to Xing Muchun, "Old Xing, Old Xing, I'll have to trouble you to supervise and direct the next few rounds of targeted supplementary tests and the data finalization work. And Director Yin, please send me a copy of the test report after you finish it."

Xing Muchun nodded: "Don't worry, Mr. Chang, leave it to me."

……

The next morning, Beijing, Torch Laboratory.

The heavy door slid open silently, and Chang Haonan's dusty figure appeared at the door of the underground testing center.

Li Yabo, who had been waiting here, came forward immediately.

This time, he had been gathering his strength for a whole night, so there was no sign of fatigue on his face, only excitement to try.

"Teacher! You're back!" Li Yabo's voice was filled with excitement.

"Where are the things?" Chang Haonan didn't say any greetings and scanned the laboratory with sharp eyes.

"This way!"

Li Yabo led Chang Haonan and walked quickly to a vacuum operating platform in the center of the laboratory, which was shrouded in high-intensity inert gas and protected by multiple layers of shock and radiation protection devices.

In the center of the platform, an irregular chip that is so thin that it is almost transparent and only the size of a palm is quietly suspended in a dust-free environment.

It was a strange transparent grey, with a slightly odd iridescence around the edges when the light caught it.

But apart from this detail, the overall look... seems ordinary, even a little fragile.

"According to the 'liquid phase controlled stripping' process you proposed before you left last time," Li Yabo said quickly, "we... succeeded!"

With just one sentence, Chang Haonan confirmed his guess.

Last night on the phone, Li Yabo just reported the situation as usual.

But before he left, he had handed over the solvent formula, surface tension control parameters and stripping kinetics model to the other party.

There should be no reason to fail again.

Li Yabo pointed at the chip and said, "This is the first piece of negative refractive transparent material with a complete structure that we have successfully separated at a macroscopic scale. Although the shape is not quite regular and the size is limited, its crystal structure and optical properties, after preliminary characterization, are completely in line with theoretical expectations!"

Chang Haonan's heartbeat was beating strongly in his chest.

Just like when he first went to Shengjing No. 601 Institute more than ten years ago.

He forced himself to remain calm and asked a non-essential question in a nonchalant manner:

"How many times?"

Li Yabo immediately turned around and called up the experiment log on the control computer next to him. A long string of densely packed records scrolled on the screen:

"From the time we started trying macro separation, we performed the complete process 97 times. Of those, 70 times we successfully completed the peeling step and kept the structure basically intact."

He pointed to a highlighted mark on the screen: "After accumulating, you end up with a chip like this."

After 97 attempts, 70 successful peelings were made, and finally a qualified chip was obtained.

Chang Haonan's eyes swept over the shocking list of material consumption in the experimental records - various ultra-high purity rare metals, special substrates, customized chemical solvents, ultra-clean environment maintenance, equipment wear and tear... In just a few months,

Just for this tiny chip, the money burned is roughly estimated to be as high as 100 million yuan!

"Heh..." Chang Haonan took a deep breath and looked back at the seemingly insignificant chip. "This is probably the single material with the highest value per unit weight on Earth right now."

He walked to the operating table, put on special sensing gloves, and carefully operated the robotic arm in the vacuum environment.

A precisely calibrated green laser beam is directed obliquely from the side toward the wafer fixed in mid-air.

The images captured by the high-power microscope lens were displayed synchronously on the large screen next to it.

The moment the green laser touched the surface of the chip, its path seemed to encounter an invisible, absolutely vertical mirror, and it was "reflected" back to the same side of the space where the laser was emitted at a completely abnormal angle and in an almost completely symmetrical direction along the incident light path!

The incident light and the refracted light are on the same side of the normal!

It is definitely a negative refractive material!

This was not the first time that Li Yabo had seen this scene, but his lips were still trembling with excitement.

Chang Haonan also secretly clenched his fists.

This is not only a successful verification of the theory, but also opens the door to disruptive applications!

However, a trace of regret soon appeared on Li Yabo's face.

"Teacher, this effect... seems shocking and miraculous to us." He chose his words carefully, "but on a broader level, for decision makers and even ordinary people who need to understand its meaning intuitively, it seems... still too abstract and too microscopic."

Chang Haonan turned to look at Li Yabo, waiting for the other party's further thoughts.

“We need a more intuitive and grand way of displaying this thing so that anyone can see at a glance how amazing it is!”

Chang Haonan did not answer immediately, but his expression was full of approval.

He put his hands behind his back and paced slowly in front of the operating table.

After a few laps, he suddenly stopped.

"Yabo," Chang Haonan returned to the operating table, "Use the fastest speed and spare no expense to make me another chip of the same size and quality."

"Make... another one?" Li Yabo was stunned.

Torch Labs is indeed not short of money.

But the cost of this current production efficiency is indeed a bit outrageous.

"Yes." Chang Haonan said firmly, "Put the two wafers together, treat the edges with our special sealing material to ensure absolute sealing, leave only the thinnest gap between the two wafers, and draw an ultra-high vacuum."

He pulled out a piece of paper and quickly sketched out a simple diagram of a double-layer flat plate structure.

"Then," Chang Haonan raised his head and said word by word, "we have a 'double negative refractive flat lens'."

What Li Yabo was thinking in his heart was:

[Indeed, it is a lens worth 200 million yuan.]
