Fabrication of Single-Negative Metamaterials Based on Coplanar Waveguide

Abstract

The fabrication of the single-negative (SNG) metamaterials involving the tunable SNG metamaterials based on coplanar waveguide is investigated. First, the SNG metamaterials are fabricated by periodically loading lumped-element series capacitors and shunt inductors on coplanar waveguide. Moreover, based on it, the tunable SNG metamaterials in which the center frequency and frequency region of the SNG gap can be tuned conveniently is also realized through loading the varactor diodes in place of the lumped-element capacitors.
