Dipole-quadrupole model and multipole analysis of resonant membrane metasurfaces
Izzatjon Allayarov, Andrey B. Evlyukhin, Antonio Calà Lesina
Membrane-metasurfaces, formed by periodic arrangements of holes in a dielectric layer, are gaining attention for their easier manufacturing via subtractive techniques, unnecessity…
Strong coupling of collective optical resonances in dielectric metasurfaces
Izzatjon Allayarov, Vittorio Aita, Diane J. Roth +5
Dielectric metasurfaces can achieve strong light-matter interaction based on several types of collective (nonlocal) resonances, such as surface lattice resonances (SLRs) and quasi…
Topology optimization of a superabsorbing thin-film semiconductor metasurface
Johannes Gedeon, Izzatjon Allayarov, Emadeldeen Hassan +1
We demonstrate a computational inverse design method for optimizing broadband-absorbing metasurfaces made of arbitrary dispersive media. Our figure of merit is the time-averaged in…
Analytical model of metasurfaces comprising meta-atoms with anisotropic polarizabilities
Izzatjon Allayarov, Vladimir R. Tuz, Antonio Calà Lesina +1
A general analytical approach to the study of electromagnetic resonances of metasurfaces consisting of meta-atoms with anisotropic electric and magnetic dipole polarizabilities and…
