Wearable metasurfaces for boosting the effective area of mobile-device antennas
Mohammad M. Asgari, Xianghui Qiu, Francisco S. Cuesta +5
Wireless communications increasingly face scenarios with compact user equipments operating in propagation environments where signal blockage, absorption, and device size limitation…
Permittivity Characterization of 3D-Printed Materials at Millimeter Waves
Kamil Anıl Işık, Mohammad Mahdi Asgari, Xuchen Wang +4
In this study, we characterize the permittivity of various commercially available materials commonly used in 3D printing over the millimeter-wave frequency range of 70-110 GHz. The…
Metacrystals: Inversely-designed 3D-printed intelligent panels for 6G communications
Mohammad M. Asgari, Peter B. Catrysse, Shuai S. A. Yuan +3
Metasurfaces represent a promising platform for improving coverage in future communication systems. Passive designs are especially attractive because they need no power supply and…
Photonic time crystals: Theory and applications
M. M. Asgari, P. Garg, X. Wang +3
This tutorial offers a comprehensive overview of photonic time crystals - artificial materials whose electromagnetic properties are periodically modulated in time at scales compara…
Optical Tellegen metamaterial with spontaneous magnetization
S. S. Jazi, I. Faniayeu, R. Cichelero +5
The nonreciprocal magnetoelectric effect, also known as the Tellegen effect, promises a number of groundbreaking phenomena connected to fundamental (e.g., electrodynamics of axion…
