Investigation of Impedance Modeling for Dual Band Frequency Selective Surface (FSS) by Using Hybrid Materials

Design of a broadband electromagnetic absorbers based on TiO2/Al2O3 ceramic coatings with metamaterial surfaces

“…Many methods such as the method of moments (MoM), finite element method (FEM), Equivalent Circuit (EC) and the finitedifference time-domain (FDTD) method for analyzing periodic structures have been developed over time [21,33]. Based on transmission line theory, the theoretical reflection loss (RL) of the Single coating including FSS can be obtained by the following formula [34]:…”
