The next generations of wireless communications are promising high capacity, low latency, and high throughput, enabled by millimeter wave spectrum. Beamforming and beam steering are key requirements for millimeter wave systems due to the fundamental

We demonstrate the efficacy of periodic corrugations, fabricated as part of the radar cover to serve the dual purpose of protecting the radar circuitry and maximizing transmission in millimeter-wave automotive radars. A 2-dimensional array of square-

We present a novel, non-contact measurement technique for the characterization of conventional antenna parameters, including port reflection coefficient, gain and radiation pattern over a desired frequency range. Our method eliminates the need for an

We present a simplified Nicolson–Ross–Weir (NRW) material characterization procedure that employs only a single-port network analyzer for data collection. This approach is particularly attractive for mmW and THz applications, as it eliminates the

Multiple reflections in an extended hemispherical lens are shown to exhibit distinctly different Gaussian characters. It is demonstrated that the second- and third-order bounces of the electromagnetic fields within the electrically large lens result

We present a novel CMOS compatible plasma dispersion modulation scheme for slow wave photonic true-time-delay structure harnessing the frozen mode to enable applications in millimeter-wave (mmWave) beamforming. Leveraging the Soref–Bennett model fo

The authors present a terahertz-band imaging system using rail-based synthetic aperture radar sensing and processing. In the proposed setup, the object is inclined with respect to the transmitter and is scanned in azimuth using a motorised linear sta
