Microwave Switch based on Tunable Single Negative Metamaterials

Abstract

Abstract-The microwave switch based on tunable single negative (SNG) metamaterials was presented. Firstly, the tunable SNG metamaterial was fabricated and its electromagnetic properties were investigated. It was found that the gap properties of the SNG metamaterial can be tuned conveniently and the epsilon-negative (ENG) gap can change to mu-negative (MNG) gap by increasing external voltage. Then, the microwave switch based on the tunable SNG metamaterial was designed through exploring the transmission properties of the heterostructure constructed by the tunable SNG metamaterial and an ENG metamaterial.
