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…

Time-domain topology optimization of power dissipation in dispersive dielectric and plasmonic nanostructures

Johannes Gedeon, Izzatjon Allayarov, Antonio Calà Lesina +1

We present a density-based topology optimization scheme for locally optimizing the electric power dissipation in nanostructures made of lossy dispersive materials. By using the com…

Dynamic dielectric metasurfaces via control of surface lattice resonances in non-homogeneous environment

Izzatjon Allayarov, Andrey B. Evlyukhin, Diane J. Roth +3

Dynamic control of metamaterials and metasurfaces is crucial for many photonic technologies, such as flat lenses, displays, augmented reality devices, and beam steering, to name a…
