Scientists developed a two-photon-enhanced metasurface that cuts photon requirements for nanoscale displacement measurement ...

Abstract: The increasing demand for mobile data traffic has driven the standardization of millimeter-wave (mmWave) frequencies to address this challenge. Smart electromagnetic skins (SES) are a ...

Abstract: This paper presents a simple reflective metasurface design that can dynamically control the direction of reflected beams. Beam steering is performed by varying phase states across the ...

Having the right camouflage on the front line can make a huge difference. If our soldiers are able to detect and locate an ...
