Abstract

A multi-channeled filter based on the effect of light-tunneling through the coupled Fabry–Perot (FP) cavity resonators is proposed. The wall of FP cavity is composed of the single-negative metamateiral. Applying the transfer matrix method we analyze the transmission mechanism of the filter. By introducing the coupled FP cavity resonators at the optical and microwave frequency ranges respectively, the single resonant mode is split into some discrete resonant peaks, leading to the multichanneled filtering phenomenon. In comparison with the conventional multichanneled filters, the proposed structure is more compact and tunable. The microwave experiment results are found in agreement with simulation results.
