dc.description.abstractIn this talk, we put forward the concept of metasurface energy concentrator which can fully reflect waves incident from multiple directions into one direction. The proposed structure is based on a spatiotemporally modulated impedance sheet mounted on a grounded substrate. We show what proper traveling-wave modulations of the sheet impedance provide this functionality. We introduce a general analysis and design method based on the generalized transmission-line model. Using mathematical optimizations, we demonstrate three-port and four-port designs of energy concentrators.en
