Experimental demonstration of superdirective spherical dielectric antenna
Roman Gaponenko, Mikhail S. Sidorenko, Dmitry Zhirihin +5
An experimental demonstration of directivities exceeding the fundamental Kildal limit, a phenomenon called superdirectivity, is provided for spherical high-index dielectric antenna…
Surpassing super-radiant scattering limit in a flat split-ring resonator
Anna Mikhailovskaya, Konstantin Grotov, Dmytro Vovchuk +6
Electromagnetic scattering bounds on subwavelength structures play an important role in estimating performances of antennas, RFID tags, and other wireless communication devices. An…
Bound States in the Continuum in Multipolar Lattices
Sergei Gladyshev, Artem Shalev, Kristina Frizyuk +2
We develop a theory of bound states in the continuum (BICs) in multipolar lattices -- periodic arrays of resonant multipoles. We predict that BICs are completely robust to changes…
Excitation of a homogeneous dielectric sphere by a point electric dipole
Roman Gaponenko, Ilia L. Rasskazov, Alexander Moroz +3
Electrically small dielectric antennas are of great interest for modern technologies, since they can significantly reduce the physical size of electronic devices for processing and…
SMUTHI: A python package for the simulation of light scattering by multiple particles near or between planar interfaces
Amos Egel, Krzysztof M. Czajkowski, Dominik Theobald +3
SMUTHI is a python package for the efficient and accurate simulation of electromagnetic scattering by one or multiple wavelength-scale objects in a planarly layered medium. The sof…
Harnessing superdirectivity in dielectric spherical multilayer antennas
Roman Gaponenko, Alexander Moroz, Ilia L. Rasskazov +3
Small form-factor, narrowband, and highly directive antennas are of critical importance in a variety of applications spanning wireless communications, remote sensing, Raman spectro…
Multipole engineering for enhanced backscattering modulation
Dmitry Dobrykh, Diana Shakirova, Sergey Krasikov +6
An efficient modulation of backscattered energy is one of the key requirements for enabling efficient wireless communication channels. Typical architectures, being based on either…
Observation of supercavity modes in subwavelength dielectric resonators
Mikhail Odit, Kirill Koshelev, Sergey Gladyshev +3
Electromagnetic response of dielectric resonators with high refractive index is governed by optically induced electric and magnetic Mie resonances facilitating confinement of light…
