Experimental validation of a transformation optics based lens for beam steering

Abstract : A transformation optics based lens for beam control is experimentally realized and measured at microwave frequencies. Laplace's equation is adopted to constnict the mapping between the virtual and physical spaces. The metamaterial-based lens prototype is designed using electric LC resonators. A planar microstrip antenna source is used as transverse electric polarized wave launcher for the lens. Both the far field radiation patterns and the near-field distributions have been measured to experimentally demonstrate the beam steering properties. Measurements agree quantitatively and qualitatively with numerical simulations, and a non-narrow frequency bandwidth operation is observed. (C) 2015 AIP Publishing LLC.
