inverse design methodology is developed to optimize a sub-wavelength metadeflector structure used on an ultra-flat antenna system in Ka-band. The strategy adopted combines two ingredients : a high order HDGFD (Hybrid Discontinuous Galerkin Frequency-Domain) solver of the frequency-domain Maxwell equations coupled to a Floquet modes...

An advanced optimization strategy is deployed to design high performance nonlocal metasurface deflectors, which are used as building blocks of a low-profile 2D-beam-steering-antenna in the Ka-band for SatCom. This new methodology combines two important ingredients. The first one is the nonlocal near-field effect generated by the interactions...
