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 ...

A team led by Northwestern University and Shirley Ryan AbilityLab scientists have developed a new technology that can eavesdrop on the hidden electrical dialogues unfolding inside miniature, lab-grown ...

Abstract: This paper proposes a three-dimensional (3D) interferometer direction-finding (DF) method to address the reduced accuracy of conventional two-dimensional (2D) interferometer DF methods in ...

//The aim is practice on matrices (two dimensional arrays/vectors) and file input/output. I implemented a program which detects a combination of matrices which add up to a single matrix, given a pool ...

Abstract: Extremely large-scale antenna arrays (ELAAs) offer promising capacity gains for integrated space-ground networks, but efficient beam training under near-field spherical wave propagation ...
