Title:
STEALTH STRUCTURE AND DESIGN METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/015328
Kind Code:
A1
Abstract:
One embodiment of the present invention provides a stealth structure in which high stealth performance is implemented, wherein the stealth structure comprises a first dielectric, a front surface pattern, a rear surface pattern, a second dielectric and a rear end conductor. The front surface pattern is stacked on the front surface of the first dielectric so as to change the phase of a first transmissive electromagnetic wave moving toward the first dielectric while losing, as first loss energy, an electromagnetic wave having an objective frequency incident thereto, and has a first sheet resistance. A rear surface pattern is stacked on the rear surface of the first dielectric so as to reflect the first transmissive electromagnetic wave transmitted through the first dielectric, and has a second sheet resistance for adjusting the phase of a reflected wave reflected toward the front surface pattern. The second dielectric is disposed on the rear surface of the rear surface pattern, and the rear end conductor is disposed on the rear surface of the second dielectric so as to have a third sheet resistance for absorbing a second transmissive electromagnetic wave transmitted through the second dielectric and for losing same as third loss energy. The third sheet resistance has a value greater than that of the second sheet resistance.
