Optical Spin Effects Induced by Phase Conjugation at a Space-Time Interface
Carlo Rizza, Alessandra Contestabile, Maria Antonietta Vincenti +5
Electromagnetic temporal boundaries, emerging when the constitutive parameters of a medium undergo abrupt temporal variations, have garnered significant interest for their role in…
Exploring Aperiodic Order in Photonic Time Crystals
Marino Coppolaro, Massimo Moccia, Giuseppe Castaldi +1
We present a theoretical framework for analyzing aperiodically ordered photonic time quasicrystals (PTQCs), which are the temporal analogs of spatial photonic quasicrystals. Using…
Rapid diagnostics of reconfigurable intelligent surfaces using space-time-coding modulation
Yi Ning Zheng, Lei Zhang, Xiao Qing Chen +5
Reconfigurable intelligent surfaces (RISs) have emerged as a key technology for shaping smart wireless environments in next-generation wireless communication systems. To support th…
Harnessing the natural resonances of time-varying dispersive interfaces
Carlo Rizza, Maria Antonietta Vincenti, Giuseppe Castaldi +3
Space-time modulation of electromagnetic parameters offers novel exciting possibilities for advanced field manipulations. In this study, we explore wave scattering from a time-vary…
