On the Use of Modal Powers and Energies in the Analysis and Design of Metamaterial Structures

Abstract

This paper discusses the problem of integrating metamaterial (MTM) structures with antennas. We present a new approach based on the computation of the energies of the surface current modes by means of the theory of characteristic modes (TCM). We also introduce new simple formulation to compute the stored energy using the impedance operation of the method of moment (MoM). This analysis can be done the antenna (driven element) and the inclusion (resonant element).
