The simplest way to make stealth technology is to create material that absorbs energy. Energy is wave movement, and the material should deny the reflection. But the problem with energy absorption is that material should move that energy somewhere.
One thing that could help with that thing is the hole or channel that is in the middle of the craft. The system can use the thermal pump to create a situation where the energy travels inside the structure. There the airflow or laser ray will conduct it to wanted direction.
Chinese scientists developed a new nanolattice material, that can absorb energy. The ability to absorb energy is one of the most important things in stealth technology. The nanolattice materials can store energy in themselves.
And that thing makes it possible that energy doesn't reflect from the material. That means the material can conduct energy in the wanted direction. Or it can store energy in itself. Black color is one of the most well-known things that absorb light. The problem with the black color is that its temperature rises.
The new nanolattice material is based on the idea that the material is made of fibers. That thing maximizes the complexity of the structure. That material has a maximum possible surface area in multiple layers that causes a situation where reflection from the fibers of that material jumps inside that structure.
Every time the radiation reflects from those fibers it hits another fiber. And that fiber pulls a little part of reflection in itself. The idea is that echo cannot continue forever. Sooner or later, the structure pulls all wave movement in itself.
If material stores energy in it, that rises the free energy level in the system. Free energy is the thing that destroys the material structure. Free energy makes the destruction because it starts resonance in all atoms in the molecule. The resonance means that atoms are sending radiation that pushes other atoms away.
And also standing waves between atoms are pushing wave movement to those atoms. And finally, that thing destroys material structures. That is the problem with material that suppose to absorb energy. If energy waves hit it, that increases the energy level of those atoms.
When somebody makes material that should absorb energy, the only thing that can make the thing is to dump that energy somewhere. If the energy-absorbing material cannot put its energy load somewhere that causes destruction.
No material can stand limitless energy increase. Sooner or later, the material starts, to transmit energy overload to its environment. And in that process, the energy that travels outside forms empty holes between atoms. That is the situation where energy from outside gets access between those atoms. And that thing rips those structures in pieces.
