In this report, we present our recent work on terahertz Cassegrain reflector antenna with compact configuration and directive radiation pattern. The geometrical parameters and electrical performance of the Cassegrain reflector system are calculated and analyzed through folded optics approach, combined with feeding horn design through numerical package simulations. Analytic results of the antenna show...
In this presentation, we will demonstrate some examples of applying the transformation optics to the manipulation of electromagnetic radiations from antenna or antenna array. By designing through different kinds of coordinate transformations, the radiation direction of an omni-directional antenna could be modulated through a metamaterial cylindrical shell, and conformal antenna array located on an...
