Ghost line waves
Massimo Moccia, Giuseppe Castaldi, Andrea Alù +1
Time-harmonic electromagnetic plane waves in anisotropic media can exhibit complex-valued wavevectors (with nonzero real and imaginary parts) even in the absence of material dissip…
Spectral-domain method of moments for the modal analysis of line waveguides
Giampiero Lovat, Walter Fuscaldo, Massimo Moccia +3
A rigorous full-wave modal analysis based on the method of moments in the spectral domain is presented for line waveguides constituted by two-part impedance planes with arbitrary a…
Rapidly time-varying reconfigurable intelligent surfaces for downlink multiuser transmissions
Francesco Verde, Donatella Darsena, Vincenzo Galdi
Until now, researchers in wireless communications have mainly focused their attention on slowly time-varying designs of reconfigurable intelligent surfaces (RISs), where the spatia…
Spin-controlled photonics via temporal anisotropy
Carlo Rizza, Giuseppe Castaldi, Vincenzo Galdi
Temporal metamaterials, based on time-varying constitutive properties, offer new exciting possibilities for advanced field manipulations. In this study, we explore the capabilities…
Multiple actions of time-resolved short-pulsed metamaterials
Giuseppe Castaldi, Carlo Rizza, Nader Engheta +1
Recently, it has been shown that temporal metamaterials based on impulsive modulations of the constitutive parameters (of duration much smaller than a characteristic electromagneti…
Modeling the Mutual Coupling of Reconfigurable Metasurfaces
Marco Di Renzo, Vincenzo Galdi, Giuseppe Castaldi
Recently, a circuits-based approach for modeling the mutual coupling of reconfigurable surfaces, which comprise sub-wavelength spaced passive scattering elements coupled with elect…
