Computer Model of a Frequency-Selective Surface on Mushroom-Shaped Metamaterial

Abstract

This paper presents a computer model of a FSS based on mushroom-shaped metamaterial. The model is based on the calculation of equivalent distributed inductance and distributed capacitance of the unit cell of the surface according to its geometric dimensions. The computer model is realized as the “META” program based on MathCAD ver.15 software and provides an opportunity to investigate the dispersion characteristics of the frequency-selective surface of a “Maltese cross” mushroom-shaped metamaterial.
