Equivalent Circuit Model Proposal Applied to Frequency Selective Surfaces

Frequency selective surfaces' (FSS) representation with an equivalent circuit composed of lumped elements is very useful in the design stage, where it is desirable to know in a quick way if a FSS is able to give a fixed frequency response. The final aim will be to obtain an equivalent circuit that fits the simulated FSS response with the proposed LC circuit. The method will be validated with a metallic ring on a dielectric substrate
