Abstract: The design of complex metasurfaces (MTS) is usually done in two steps: a) design of the surface impedance profile; b) realization of unit-cells, often using a periodic approximation. In this ...

Abstract: Extremely large-scale multiple-input multiple-output (XL-MIMO) with orthogonal frequency division multiplexing (OFDM) transmission can provide unprecedented improvement in spectral ...
