Abstract: In this letter, we propose a period-weighted shared-aperture (PWSA) method to achieve multifocusing using tensor holographic impedance metasurfaces (THIM). A focusing phase expression is derived, and the period of impedance variation is employed as a… read more here.

Published in 2025 at "IEEE Transactions on Microwave Theory and Techniques"

DOI: 10.1109/tmtt.2024.3439330

Abstract: Conventional holographic impedance metasurfaces with large apertures usually have extremely narrow bandwidths, limiting their applications for broadband orbital angular momentum (OAM) waves. In this article, a new wideband, optically transparent low-profile holographic impedance metasurface is… read more here.
