- W4213305439 abstract "In this contribution, we describe the design of a self-filtering horn antenna based on the innovative features of multipolar all-dielectric metasurfaces. We first analyze the scattering response of a dielectric core-shell meta-atom with a strong permittivity contrast and we show how such a geometry allows a fine control of the spectral positions of the dipolar and quadrupolar Mie resonances. Then, we describe how it is possible engineering the electric and magnetic surface currents flowing on the metasurface for achieving a band-pass filtering response. Finally, we show how such high-Q filters are suitable for the integration in an horn antenna and, thus, for the implementation of an ultra-selective filtenna. A realistic design based on commercial materials is proposed and checked with full-wave simulations." @default.
