Simulation Metamaterial Based FSS with Internal Boundary Split Ring

Abstract: Frequency selective surface (FSS) is a periodic surface with identical two-dimensional arrays of elements arranged on a dielectric substrate. An incoming plane wave will either be transmitted (passband) or reflected back (stopband), completely or partially, depending on the nature of array element. This occurs when the frequency of electromagnetic (EM) wave matches with the resonant frequency of the FSS elements. Set of simulation optimization were carried out with single split FSS, split with internal boundary and dual split FSS with internal boundary. Metamaterial based substrate with perfect electric conductor (PEC) layer was used to make the FSS design. It was observed from the results that with internal boundary and dual split ring based FSS has higher resonance frequency.
