We propose a novel quasi-optical topology to enable ultra-wideband on-wafer characterization in the THz regime. Using quasi-optical components, we implement a high-performance directional coupler and a noncontact probing scheme, to interrogate on-waf

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

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
