Geiger-mode avalanche photodiodes (GM-APDs) are highly sensitive light detectors, capable of detecting single photons.

Abstract: This article proposes a novel demodulation approach for fast measurement of seawater temperature, utilizing the dual-wavelength differential cross-multiplication (DWDCM) algorithm. The ...

Abstract: In this communication, we propose a low-sidelobe dual-polarized waveguide slot phased array antenna, operating in the X-band, based on array coding techniques. The horizontal polarization ...
