Abstract

We propose a multilayer unit cell with amixture of metal and dielectric materialsto configurate the encoding metamaterials. The higher transmittance with more than 0.9 and the phase change from 0°to 360°are critically designed for unit cells correspondingto different encoded particles. Here, the parallel encoding method and the checkerboard encoding method are adopted to construct the encoding metamaterials by using corresponding encoded particles. The scattering energy for co-polarization transmitted electromagnetic wave canbe flexibly manipulated by using the designed encoding metamaterials. The far field scattering of transmitted wave is numerically simulatedby using finite integral method. According to the generalized Snell's law, it is found that the calculatedtheoretical deflection angles agree well with that of numerical simulation..
