Abstract

In this paper, we report the design and analysis of a metamaterial for multiband microwave applications with epsilon negative (ENG), mu-negative (MNG), and negative effective refractive index characteristics. The suggested metamaterial comprises a 0.16 cm thick FR-4 substrate with a unit cell dimension of 1 cm × 1 cm. Design and simulation of the proposed metamaterial structure are performed with the Finite element method using COMSOL Multiphysics software in the frequency range of 1-15 GHz. The effective medium parameters i.e., effective permittivity, effective permeability and effective refractive index were calculated using Nicolson Ross weir method. Further, its Effective medium ratio (EMR), which is obtained 9.9 at 3 GHz operating resonance frequency, indicating the compactness of the structure.
