Methods for extension of the rejection band of microwave devices on the basis of planar modified mushroom-shaped metamaterial structures

Abstract

Methods for extension of the rejection band of microwave devices on the basis of planar modified mushroom-shaped metamaterials comprising either two-layered topological structures with frequency-selective surfaces or multilayer bulk structures with intermediate layers containing split-ring resonators are proposed. Computer simulation of such devices, clearly demonstrating a twoto six-fold extension of the rejection band is performed. Experimental results confirming the results of numerical simulation are presented.
