Frequency Selective Rasorber With Low Insertion Loss and Ultra‐Broadband Scattering Reduction
Advanced Physics Research, EarlyView.We present a dual‐polarization broadband frequency selective rasorber featuring a transmission window in the middle of its absorption band. The proposed FSR achieves a –10 dB reflection band over 3.68–16.94 GHz with a fractional bandwidth of 128.6%, featuring a minimum insertion loss of 0.3 dB at 10.3 GHz.
