Demonstration of a Polarization-Agnostic Geometric Phase in Nonlocal Metasurfaces
Adam Overvig, Yoshiaki Kasahara, Gengyu Xu +1
Symmetry-driven phenomena arising in nonlocal metasurfaces supporting quasi-bound states in the continuum (q-BICs) have been opening new avenues to tailor enhanced light-matter int…
Broadband Coherent Wave Control Through Photonic Collisions at Time Interfaces
Emanuele Galiffi, Gengyu Xu, Shixiong Yin +3
Coherent wave control exploits the interference among multiple waves impinging on a system to suppress or enhance outgoing signals based on their relative phase and amplitude. This…
Approach to the Analysis and Synthesis of Cylindrical Metasurfaces with Non-circular Cross Sections Based on Conformal Transformations
Gengyu Xu, George V. Eleftheriades, Sean V. Hum
We present methods for analyzing and designing cylindrical electromagnetic metasurfaces with non-circular cross sections based on conformal transformations. It can be difficult to…
