Stacked Time-Varying Metasurfaces
Mostafa Movahediqomi, Sergei Tretyakov, Viktar Asadchy +1
Spatiotemporal metasurfaces offer unique opportunities for wave manipulation, however, their practical realization is often constrained by the requirement for in-plane spatial modu…
Terahertz frequency conversion at plasma-induced time boundary
Yindong Huang, Bin Zhou, Aijun Xuan +8
We report on the frequency conversions of terahertz (THz) waves at ultrafast time boundaries created via femtosecond laser-induced air-to-plasma phase transitions. Our combined exp…
Photonic time crystals assisted by quasi-bound states in the continuum
P. Garg, E. Almpanis, L. Zimmer +8
Photonic time crystals are a class of artificial materials that have only recently been explored. They are characterized by the ultrafast modulation of the material properties in t…
All-Angle Scanning Leaky-Wave Antennas and Surface-Wave Routing by Reconfigurable Metasurfaces
Yongming Li, Xikui Ma, Viktar Asadchy +1
In this work, we show that propagating waves can be fully converted into surface waves and back using geometrically periodic arrays of simple electrically small metal elements load…
Simultaneous Angle-of-Arrival Sensing and Anomalous Deflection with Aperiodically Loaded Patch Arrays
Mostafa Movahediqomi, Sravan K. R. Vuyyuru, Grigorii Ptitcyn +4
We propose and numerically demonstrate a reconfigurable patch antenna array that enables simultaneous incident wave sensing and anomalous reflection without prior knowledge of the…
