Simulation analysis of frequency selective surface with high power handling capability
An analysis of frequency selective surfaces (FSSs) with high power handling capability is presented in this paper. Maximum field enhancement factor (MFEF) is applied to quantify the power handling capability of FSSs. The effects of various design parameters on the MFEF and frequency response of FSSs are investigated using split finite-difference time-domain (split-FDTD) method. It is observed that the unit cell size, gap width and distance between two slot arrays are the main factors which affect the peak power handling capability of FSSs. Through the parameters optimization, the MFEF of FSSs decreases about 1.8 times comparing to the FSSs without optimization. The calculated frequency response and MFEF demonstrate three advantages of the FSS after optimization: insensitivity to the angle and polarization of incident waves, a relatively flat pass-band and lower MFEF. This kind of FSSs can be especially useful for airborne radar-dome which might be attacked by high power electromagnetic pulse weapons.
