A guided tour in metasurface land: Discontinuity conditions, design and applications

The paper presents an overview of the recent research on metasurfaces performed in the author's group. This covers the introduction of bianistropic Sheet Transition Conditions (STCs), the subsequent elaboration of a general synthesis technique based on surface susceptibility tensors, the complementary elaboration of Finite Difference (FD) and Finite Element (FE) computational schemes for analysis, and, based upon this solid foundation, the development of a host of novel applications across the whole microwave to optical range of the electromagnetic spectrum.
