A Surface Impedance Model for a Microstrip-line based Metasurface

The design and results of mantle cloaking for a metallic cylinder are investigated. First, a single homogeneous surface impedance coat is considered. An analysis of the scattering harmonics of the bare and cloaked cylinder is performed and the effect of different surface impedance values on the scattered field are discussed. Then, a single in-homogeneous metasurface coat, based on a width-modulated microstrip line, is analysed and compared with such surface impedance model
