I turned into a loli and didn't want to be discovered, so I had to become an assassin.

The pterosaur Black Beak had already adjusted the formation under Luo Li's control and aimed at the tank troops, forming high-power microwave pulses in a skillful way.

"Sure enough, the source of this electromagnetic pulse really comes from the black mist monster."

There was no time to do too much emotion, and Ouyang Feng, who found Zhong Yu halfway and applied to hide in the tank unit, immediately stood up at this moment.

The heart skill was activated, and a strange light began to bloom in his eyes.

There are many ways to block an electromagnetic pulse, but first of all, it can be confirmed that it is formed by high-power microwave pulses.

Then as long as correspondingly, reducing its frequency to make it low to a certain extent can naturally eliminate the electromagnetic pulse.

So how to reduce the frequency?

In the normal air of this world, the wave speed is always certain, that is, 3.0 * 10^8 m/s, which is equivalent to the speed of light

Then, in theory, the frequency can be reduced by simply increasing the wavelength.

Of course, that is only theoretical, and there are not many such cases in the history of facts.

Because the order of formation is different, not to mention, its frequency is too high, and it is not advisable to increase the wavelength scheme.

Then in Ouyang Feng's head, the means that can resist electromagnetic pulses are roughly divided into two types.

One is interference, the other is shielding.

Being a gaze, but also a gaze with real material.

His time in the library is not long, correspondingly, the breadth of knowledge has also been duly improved, coupled with his own memory palace memory method, the memorization of knowledge points is also quite profound.

Regarding the first scheme, the spread spectrum system has a strong anti-interference ability, for the direct spread signal, theoretically can be expanded by the signal spectrum to obtain any large processing gain, but this anti-interference ability depends on several performance and working environment of the system, in the current situation is obviously not appropriate.

Then there is only another solution, which is shielding.

The shielding itself is also a method of confineing electromagnetic waves to a certain area through shields such as shells, boxes, and plates made of metal.

In electronic devices and electronics, electromagnetic interference energy is transmitted through conductive and radiative coupling.

Therefore, shielding is suitable for electromagnetic pulses.

Ouyang Feng's mental skills are related to machinery, and he is familiar with the principle of shielding, so using corresponding countermeasures to crack has also become a possible means.

The knowledge points buried in the memory palace were put back on the table by Ouyang Feng.

The principle of electromagnetic shielding is that the metal shield shields the far field of the radiation interference source through the reflection and absorption of electromagnetic waves, that is, the electric field and magnetic field components generated by the field source are shielded at the same time.

Ouyang Feng sorted out the principle and raised it with one hand.

An invisible transparent film covered the entire tank unit, blocking all the high-power microwave pulses formed by the combined force of the pterosaur black beak.

The internal composition of this transparent film is mainly based on metal materials with high conductivity and high magnetic permeability, although it is temporary and virtual, but in the short term, it is still available at the practical level.

The membrane is not completely independent and suspended above the tank troops, but has a standard and good grounding wire, as well as extremely tight protection at all the fine vents.

Why apply tight protective measures between the pores?

Quite simply, because the frequency increases, the wavelength becomes comparable to the size of the hole gap on the shield, resulting in the leakage of the hole gap of the shield body becoming the most critical control element of electromagnetic shielding.

This can ensure that under good grounding conditions, the influence of electric field induction between the two devices can be reduced, and the interference generated by the interference source will be terminated by the shield of the good conductor, so as to ensure that the electromagnetic pulse is difficult to reach the sensitive components inside the equipment.

To put it simply, Ouyang Feng dragged all the effects of the electromagnetic pulse to his fictional invisible machine, thus protecting the tank troops below to a certain extent.

The tank troops below witnessed the sound waves created by the combined efforts of the pterosaur Black Beak in a brief period of mental tension and did not have a noticeable effect on their equipment, and even if there were, it was only a little, and it was not a problem at all from the level of use alone.

After all, they are used to the slightly problematic instruments, and every soldier must be prepared for the sudden scrapping of instruments on the battlefield, rather than becoming a wooden man standing and beating once the instrument or vehicle is scrapped.

Contingency measures are the method that each unit will train individually, but this is better not to happen.

And at this moment, it was Ouyang Feng who gave them the best situation.

"It's awesome."

This is what the soldiers have in their hearts.

After all, whether you will use a mobile phone, and the difficulty of temporarily manufacturing a mobile phone, that is completely one day after another, there is nothing to compare.

There is no advanced vocabulary for embellishment, and it is enough to directly deduct 666 to the gazer boss.

Of course, they did not forget their duties, and while ensuring that the electromagnetic pulse above did not have a noticeable effect, they continued to move forward steadily despite their brief shock and euphoria.

This scene was naturally seen clearly and clearly by Luo Li in the distance, with the vision of the pterosaur black beak.

A little surprised, but still expected.

"Gaze... I haven't seen it for a long time, such a powerful gazer, but it's not a big problem. "

The original method didn't work, which is normal.

Even if there is a saying that there is a trick that is eaten all over the world, any truth has its necessary premise, and it is clear that the premise of this sentence does not apply in all cases.

At least, it doesn't apply to the fact that others are not fools.

There is no way, even if this situation is expected, it does not mean that Luo Li will definitely be able to crack Ouyang Feng's ability, it can be, but the effect is not obvious, the most important thing is that the cost performance is not high.

Then let them move forward steadily, or focus on appropriate sexual harassment.

Thinking of this, Luo Li decided to withdraw the control of the pterosaur Black Bead, and then focused his attention on the battle situation in front of him.

With Bai Zhao and the others being pinned down by the three black beaks, Luo Li is now fully capable of solving all the support members who were originally used to block the rest of the black beaks.

This makes it easy to change the situation from encirclement to counter-encirclement.

If the high-level human level did not send someone to save them, Luo Li was ready to accept all of them unceremoniously.

After all, there is a saying that there is no garbage in the world, only misplaced treasures.
