Design of Collimator and Optical Splitter Based on Near-Zero-Index Materials
Due to the zero phase variation and impedance matching to free space, zero-index material is used to control the electromagnetic radiation patterns. We design a new type collimator and optical splitter structure based on near-zero-index material. Such structures can implement the beam transformation from cylindrical wave to parallel wave and optical splitting. The numbers of the splitting beams,the width and the direction of the beams can be correctly tailored. All the simulation results show that our designs have perfect performance.
