Resonance-Enhanced Time Reflection at Photonic Temporal Interfaces
Zeyuan Li, Hammam Bahurmuz, Mohamed H. Mostafa +5
Photonic temporal interfaces enable dynamic control of light fields, yet strong time reflection at optical frequencies remains challenging because conventional approaches demand la…
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…
Non-Reciprocal Dynamic Metasurface Antenna: Practical Multiport-Network Modeling and Optimization for Multi-User Interference Resilience
Shuai S. A. Yuan, Jean Tapie, Bahman Amrahi +2
Channel reciprocity fundamentally limits full-duplex (FD) base stations due to multi-user co-channel interference. We examine the potential of deploying a non-reciprocal dynamic me…
Efficient Scattering Synthesis for Beyond-Diagonal Non-Local RISs Coupled with Passive Load Networks
Sravan K. R. Vuyyuru, Francisco S. Cuesta, Viktar S. Asadchy +2
Realizing advanced functionalities with high efficiencies via reconfigurable intelligent surfaces (RISs) and reflectarrays requires configurations with strong electromagnetic non-l…
