“…Frequency selective absorber (FSA) [6][7][8][9][10] has been widely researched and employed in the field of RCS reduction due to its excellent absorption efficiency within the frequency band range outside the passband. In general, the ideal frequency response of a FSA is as follows: for the window of transmission or reception signals, representing the operating frequency band of the radar antenna, electromagnetic waves can pass through with low insertion loss, at which point S21 = 1 and S11 = 0.…”

“…7 Frequency-selective absorbers have been reported recently in the literature to reduce RCS at a given frequency. 8 Like other absorbing coatings, frequencyselective MSAs suppress specular reflections and reduce RCS, although achieving it within a quasiplanar structure. Such structures can be also used (e.g., as protective sheets) in industrial environments that use powerful microwave signals with a fixed frequency.…”

“…The advent of absorptive frequency-selective reflection (AFSR) type structure has serve for a substantial application in the realization of a low RCS antenna system [12], [13]. The AFSR structure is a specialized category of frequencyselective surface (FSS), which features a notch shaped reflection band along with one-/two-sided absorption bands.…”
