The present invention attached to the inventor of the radio wave absorbent structure is excellent in radio wave absorption stealth is to be possible without changing the form of the object to the military purpose aircraft, ship, missile, etc. have a possible stealth radar avoidance wave absorption structure in the object just as there is had the stealth, wave absorption principle of a radio wave absorbing structure using the wave propagation properties of the length of one side than the wavelength of the radio wave i of the small square, regular hexagon or polygon hole than the half-wave aluminum pillars principle of a radio wave by attaching to the side like a net absorption of radio waves by preventing vibration while passing through the hole and at this time also create columnar shorter longer than the half-wave through a performance test, and the height of the material for the structure to absorb the electric wave a metal that reflects radio waves and aluminum is affordable and well .
Excellent stealth performance of existing aircraft, ship, missile, etc. at a lower cost than conventional to attach the radio wave absorbent structure without any shape change to the radio absorptivity very superior to the conventional radio wave absorbent paint reduce radar reflection area according to the present invention can be had, and it also can be used, and the electromagnetic wave propagation block is determined would be helpful in enhancing national defense.
