Homogenization and characterization of metasurfaces: General framework

摘要

In this overview talk we will present a methodology for homogenization and electromagnetic characterization of general bianisotropic metasurfaces. Compared to the two known alternative theories developed by the joint group of profs. Holloway and Kuester and the joint group of profs. Simovski and Tretyakov, this generalized framework allows characterization of both periodical or amorphous metasurfaces formed by bianisotropic unit cells located at interfaces between two different media or on a substrate. The developed analytical theory can be used in the analysis and synthesis of metasurfaces for a wide variety of applications.
