Mie Optical Computing
Vsevolod Kleshchenko, Vladimir Igoshin, Costantino De Angelis +1
Optical computing is emerging as a promising paradigm for next-generation information processing. Diffractive optical processors rely on spatially distributed trainable degrees of…
Resonant state expansion for acoustic resonators. Part I. Eigenvalue problem
Egor Domoratskii, Vladimir Igoshin, Nikolay Solodovchenko +4
Resonant-state expansion (RSE) is a powerful modal framework for the perturbative analysis of open resonant systems, providing direct access to complex eigenfrequencies and eigenmo…
Resonant state expansion for acoustic resonators. Part II. Scattering problem
Egor Domoratskii, Vladimir Igoshin, Nikolay Solodovchenko +4
We develop a resonant-state expansion formulation for acoustic scattering by individual resonators. The scattered pressure and particle-velocity fields are expanded over the resona…
Inverse design of Mie resonators with minimal backscattering
Vladimir Igoshin, Alexey Kokhanovskiy, Mihail Petrov
Manipulation and engineering of light scattering by resonant nanostructures is one of the central problems in optics and photonics. In this work, we theoretically study the effect…
