Numerical Study of a New Type of Tunable Srr Metamaterial Structure

Abstract

A new structure for magnetic resonance called tunable SRR has been designed by introducing a short bar into a single-ring SRR. We systematically study the magnetic response of single-ring, double-ring and tunable SRRs. The dependence of the magnetic resonance frequency of the tunable SRR on the length, width of short bar and distance between the short bar and SRR is examined. We also study the transmission characteristic of LH structures composed of tunable SRR and wires, and verify the LH transmission peak can be tuned by adjusting the distance between the short bar and SRR.
