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...

Dans cet article, une lentille imprimée en technique FDM est éclairée par un réseau de patch pour réaliserune antenne directive reconfigurable sur un angle d'ouverture de +/-12°. Une base compacte est utiliséepour réaliser la mesure à 27GHz et valider les performances en gain de la structure proposée.
