Abstract

Almost extreme control of electromagnetic fields is achievable using metamaterial and metasurfaces. This chapter details design techniques, challenges, and possible solutions of diffraction type, transmitted, specular, and absorptive type of metasurfaces in an attempt to achieve extraordinary device performance for a particular application. In metasurfaces, the transmission can also involve scattering using the phenomenon of diffraction, which is directly defined by the properties of the metasurface. Electromagnetic wave scattering patterns dependent on the incident polarization can be tailored by the encoded metasurfaces with regular sequences. On contrast, polarization-insensitive diffusion-like scattering can also be successfully achieved by digital metasurface encoded with randomly distributed coding sequences leading to substantial suppression of backward scattering in a broadband microwave frequency. It is believed that controlling the electromagnetic waves reflected from and transmitted through intelligently designed metasurfaces can shape the future of the communication industry.
