Investigation of RCS dependence on chirality for a chiral cylinder buried below slightly rough surface

Double‐layer ultra‐thin artificial magnetic conductor structure for wideband radar cross‐section reduction

“…Using (6), the RCSR data of the chessboard surface (Fig. 1c) using the best values of the design parameters, is determined and shown in Fig.…”

“…Passive cancellation is related to the amplitude and phase difference between the scattered waves from two different parts of the target which causes the RCS to be decreased [1]. It consists of different methods such as shaping [4,5], object coating [6,7], using radar absorbent material (RAM) [8][9][10], and using surfaces including frequency selective surfaces [11], artificial magnetic conductors (AMC) [12][13][14][15][16][17][18][19][20][21], and EM band gap (EBG) [22][23][24][25][26][27][28] with or without vias. Furthermore, meta-surfaces are used for RCSR of antennas, such as in [29], in which a double-layer meta-surface is designed for RCSR.…”
