The Study on the Periodic Left-Handed Materials of Convex-SRRs Structure

Abstract:

The split ring resonators is the basic structure unit ,it is important constituent part of periodic left-handed materials (LHMs).The convex split ring resonators (convex-SRRs) structure is the new SRRs, the new periodic LHMs are made of convex-SRRs structure unit.The convex-SRRs structure is arranged periodically 3 * 4 matrix along XOY plane and arranged periodically 3 * 2 * 1 matrix along the YOZ plane. These convex-SRRs structure units in space periodic aligned to the prism shape, the new artificial materials come into being.In order to prove that the convex-SRRs structure periodic materials are left-handed materials (LHMs), the microwave transmission and negative refractive are simulated using the materials of convex-SRRs structure prism. First the permeability and permittivity of convex-SRRs structure materials are negative value by simulation the microwave transmission, this is the symbol of the left hand material properties. Second by simulation, prism’s experiment of convex-SRRs structure materials has a negative refractive effect, These simulations demonstrate that the materials of convex-SRRs structure periodic arrangement are LHMs.
