Design and optimization of Frequency Selective Surfaces (FSS) [PDF]
, 2019 The analysis method for Frequency Selective Surfaces (FSS), the spectral-domain Method of Moments (MoM) is improved to be applicable to normal incidence. A more efficient optimization algorithm, Differential Evolution Strategy (DES) is proposed to optimize the standard, non-irregular FSS unit-cell and dielectric properties.
