Arbitrarily rotating polarization direction and manipulating phases in linear and nonlinear ways using programmable metasurface

Independent controls of various properties of electromagnetic (EM) waves are crucially required in a wide range of applications. Towards this goal, scientists in China proposed the concept and general theory of space-time-polarization-coding (STPC) metasurface, which adds the functionality of arbitrarily controlling polarization direction compared to space-time-coding (STC) metasurfaces. The proposed approach has a wide range of applications in various areas, such as imaging, data storage, and wireless communication.

NYU Tandon School of Engineering and Indian Institute of Technology Kanpur announce seven joint research projects launching their new partnership

NYU Tandon School of Engineering and Indian Institute of Technology Kanpur (IIT Kanpur) have unveiled their inaugural roster of collaborative research projects, the first such initiatives under the partnership that NYU and IIT Kanpur established last year. The projects aim to advance fields including cybersecurity, biotech, AI, robotics, and wireless communications.

This technology could bring the fastest version of 5G to your home and workplace

A new technology developed by electrical engineers at UC San Diego might one day allow more people to have access to 5G connectivity that provides ultra-fast download speeds along with widespread, reliable coverage—all at the same time. The technology enables millimeter wave signals to overcome blockages while providing high throughput.

Detecting, Exploiting Non-Line-of-Sight Paths for Terahertz Signals in Wireless Communications

After developing a link discovery method in 2020 using terahertz radiation, Rice and Brown researchers addressed what would happen if a wall or other reflector creates a non-line-of-sight path from the base station to the receiver. In APL Photonics, they consider two different generic types of transmitters and explore how their characteristics can be used to determine whether an NLOS path contributes to the signal received by the receiver.
