A team of researchers at Penn State have devised a new, streamlined approach to designing metasurfaces, a class of engineered materials that can manipulate light and other forms of electromagnetic ...

Metasurfaces, as 2D artificial electromagnetic materials engineered at subwavelength scales, enable efficient manipulation of electromagnetic waves far beyond natural materials, bridging the gap ...

This paper introduces a broadband polarization conversion reconfigurable metasurface retroreflector, which is made up of periodically arranged, specially engineered broadband polarization conversion ...

Holography—the science of recording and reconstructing light fields—has long been central to imaging, data storage, and encryption. Traditional holographic systems, however, rely on bulky optical ...

Abstract: A chessboard-shaped polarization conversion metasurface (PCM) is designed based on the proposed miniaturized concept. This metasurface utilizes the principle of phase cancellation to ...

Fig. 1. (a) THz optical path diagram based on metasurface. By controlling the phase delays of LCP and RCP waves by unit cells, metasurface can transmit the LCP and RCP components of the incident ...
