METHOD OF DESIGNING STEALTH STRUCTURE AND STEALTH STRUCTURE DESIGNED THEREBY

摘要

One embodiment of the present invention provides a stealth structure in which high stealth performance is implemented. Here, the stealth structure includes a first dielectric, a front pattern, a back pattern, a second dielectric, and a rear conductor. The front pattern is stacked on the front surface of the first dielectric to change the phase of the first transmitted electromagnetic wave moving toward the first dielectric while losing the electromagnetic wave having the target frequency incident as the first loss energy, and has a first surface resistance. The back pattern is stacked on the back surface of the first dielectric to reflect the first transmitted electromagnetic wave passing through the first dielectric, but has a second surface resistance to adjust the phase of the reflected wave reflected toward the front pattern. The second dielectric is disposed on the rear surface of the rear pattern, and the rear conductor is disposed on the rear surface of the second dielectric and has a third surface resistance for absorbing the second transmitted electromagnetic wave transmitted through the second dielectric and losing it as a second loss energy. . The third sheet resistance has a larger value than the second sheet resistance.
