Equivalent material parameter extraction of double strip loaded waveguide

Abstract

Equivalent material parameters of a periodic waveguide structure loaded with double strips printed on dielectric has been extracted. It shows a passband where the relative permittivity and permeability are simultaneously negative also called as double negative (DNG) passband. Full-wave Hybrid MoM-Immittance Approach is employed for the material parameter extraction validated by independent Ansoft High Frequency Structure Simulator (HFSS) extracted results.
