“…A typical single-FSS-layer CA absorber includes a lossy periodic array of resonators and a metal-backed spacer. Its bandwidth-to-thickness ratio and insensitivity to angle of incidence can be simultaneously improved by adding a dielectric cover, which serves as an impedance transformer [10], [28]. Exhaustive search on such an absorber requires m n1+n2+n3 full-wave simulations in total, where m is the sample size for each design variable, and n 1 , n 2 , n 3 are the number of design variables for each part of the FSS, namely the unit-cell resonator geometry, the lossless dielectrics and the sheet resistance.…”
