Novel functionalities enabled by asymmetric reconfiguration in VO2-dielectric metasurfaces
P. Hostalet-Vicent, L. M. Máñez-Espina, K. Schouteden +5
Bianisotropic metasurfaces provide electromagnetic functionalities that cannot be achieved through electric and magnetic responses alone, enabling asymmetric scattering, directiona…
Boosting Sensing Performance through Near-Field Engineering in Low-Q Metasurfaces
José Antonio Álvarez-Sanchis, Luis Manuel Máñez-Espina, Teresa Mengual Chuliá +2
Dielectric metasurfaces have introduced a new paradigm for substance detection by exploiting their resonant properties to enhance light-matter interaction. This enhancement can be…
Strong Mode Coupling via Quasi-Bound States in the Continuum in Bianisotropic Metasurfaces
Luis Manuel Máñez-Espina, Bahman Amrahi, Viktar Asadchy +1
Electromagnetic mode coupling plays a key role in many resonant effects in nanophotonics. This coupling is also responsible for the appearance of bianisotropy, where electric and m…
Giant bias-free nonreciprocity for unpolarized light via synthetic motion
L. M. Máñez-Espina, B. Amrahi, I. Faniayeu +4
Reciprocity breaking at optical frequencies typically relies on bulky magnets, dynamic modulation, or nonlinearities, all of which hinder chip-scale integration and the handling of…
