We present a method for the mitigation of quantization lobes in single-bit reconfigurable reflective surfaces (RRSs). Typically, RRSs are planar beamforming structures consisting of hundreds or thousands of antennas with integrated tunable switches.

We present a topology for suppressing quantization lobes in 1-bit reconfigurable reflective surfaces (RRSs). RRSs are planar surfaces that redirect the imping waves to the desired direction through phase modulation. For single-bit modulation, plane-w

A simple numerical approach is presented to estimate rough surface scattering. We measure the roughness parameters of rough surfaces and then import them into a 2D model to compute the scattered fields under various surface illuminations. The validit

We investigate the propagation losses in terahertz (THz) non-line-of-sight (NLoS) imaging and compare the performance to the optical counterpart. NLoS imaging exploits the multiple reflections of electromagnetic waves from surrounding surfaces to rec

We propose the design of a quasi-optical directional coupler toward the implementation of the first quasi-optical terahertz (THz) vector network analyzer (VNA). With the proper use of lenses and splitters, we design a quasi-optical topology that isol
