Cosmic rays are extremely fast, charged particles that travel through space at nearly the speed of light. The Amaterasu particle was detected in 2021 by the Telescope Array experiment in the U.S. It ...
Atom tamers Top left: Schematic of how a metasurface shapes a single beam of light into multiple tightly focused beams in a single step. These beams form a series of optical tweezers to trap ...
Abstract: A low-cost, low-profile, electronically controlled millimeter-wave antenna array with two-dimensional wide-angle beam scanning capability is presented. It consists of a planar waveguiding ...
Abstract: This paper presents a CMOS readout circuit for three-dimensional (3D) integration of single-photon avalanche diode (SPAD) arrays. The compact pixel architecture incorporates active quenching ...
