An Integral Equation Approach to Optimize Surface Waves for Lossless and Passive Omega-Bianisotropic Huygens’ Metasurfaces

Abstract

We propose a surface-wave enabled metasurface design algorithm which uses an integral equation approach to optimize the surface waves. These surface waves are used to redistribute the power, thus increasing the range of possible field transformations when using lossless and passive omega-bianisotropic Huygens’ metasurfaces. The novelty of the approach is the ability to be applied to arbitrary metasurface shapes. The validity of the method is demonstrated for a fundamental case.
