Experimental study on multichannel-based quasi-one-dimensional photonic crystals containing negative-index materials

Abstract

In this paper, multichannel-based quasi-one-dimensional photonic crystal containing negative-index materials is investigated by both numerical simulation and microwave experiments. The relationship between gap properties and the connectivity originated from quasi-one-dimensional geometry is analyzed. The results show that due to the introduced parallel multiple channels large bandgap can be obtained, with total length along propagation direction of photonic crystal unchanged in the mean time. Therefore, multichannel-based quasi-one-dimensional photonic crystal containing negative-index materials may provide more possibilities to the design of compact optic and microwave devices with higher efficiency
