This article presents a CMOS-based, ultra-broadband frequency-modulated continuous-wave (FMCW) radar using a terahertz (THz) frequency-comb architecture. The high-parallelism spectral sensing provided by this architecture significantly reduces the ba

Sub-THz radars in CMOS are attractive in vital-sign and security-sensing applications, due to their low cost, small size, and high resolution. The commonly used bistatic configuration, however, leads to serious beam misalignment between TX and RX, wh

A dual-frequency reconfigurable reflectarray (RRA) is proposed and verified experimentally. The RRA consists of 1600 electronically controllable elements. By integrating only a single PIN diode, the proposed element is capable to operate at two worki

In this paper, a generalized phase conjugation (PC) principle is derived through both the wave interpretation and the quantum interpretation. A harmonic-modulated nonlinear metasurface (HM-NMS) is proposed accordingly. Based on the generalized PC pri
