Implementation of effective negative ɛ transmission line in stripline technology

Abstract

In this work, a negative-ϵ equivalent response medium is proposed in stripline technology. To achieve band rejection behaviour, Complementary Split Ring Resonators (CSRR) are placed in the central conductor strip of a conventional stripline planar transmission line. Due to strong normal electric field incidence, adequate excitation of the stripline is achieved, leading to band rejection in the quasi-static resonance frequency of the CSRR particles. Full wave simulation results from our own FDTD code and measurement results are presented, showing good agreement.
