General Analysis of a Loop Antenna Located on a Uniaxial Metamaterial Cylinder

The general problem of determining the electrodynamic characteristics a circular loop antenna located coaxially on surface metamaterial cylinder is studied using integral equation method. has form perfectly conducting, infinitesimally thin, narrow strip coiled into ring and excited by given time-harmonic voltage. assumed to be filled with uniaxial surrounded an isotropic magnetodielectric. Integral equations for azimuthal harmonics current are derived solved in cases where normal waves inside have either hyperbolic or nonhyperbolic dispersion. Based solutions these equations, distribution input impedance found closed form. behavior as functions parameters discussed.
