Abstract

This paper investigates the realization of epsilon-negative and near-zero (ENNZ) metamaterial liners for below-cutoff propagation in circular waveguides using an inductively loaded thin-wire grid composed of radially and azimuthally directed wires. Full-wave parametric simulations show how parameters such as periodicity in ρ, φ, and z, along with the degree of inductive loading can alter the dispersion of the structure´s supported modes.
