Abstract

As an initial step in developing steerable mirrors for terahertz (THz) wireless communication systems, this paper describes the development of a passive planar terahertz retroreflectors based on the Van Atta array. The retroreflector is optimized and simulated using finite-element modeling (FEM) software, fabricated via a low-cost additive manufacturing method, and characterized using THz time-domain spectroscopy. Comparison to a flat metal plate shows a significant increase in retroreflectivity for off-normal angles of incidence.
