All-dielectric bianisotropic metasurfaces [PDF]

2016 10th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS), 2016
Bianisotropic all-dielectric metasurfaces are demonstrated experimentally and their properties are studied in the microwave frequency range. Such metasurfaces are composed of dielectric particles with broken symmetry that exhibit different backscattering for the opposite excitation directions.

Reconfigurable all-dielectric metasurface based on GSST

Results in Physics, 2022
Reconfigurable metasurfaces provide a new way for applications requiring dynamic tunability, such as focusing lenses, holographic displays, optical switch and so on. In this paper, a reconfigurable bi-functional metasurface is proposed.

Evolutionary optimization of all-dielectric magnetic nanoantennas

, 2019
Magnetic light and matter interactions are generally too weak to be detected, studied and applied technologically. However, if one can increase the magnetic power density of light by several orders of magnitude, the coupling between magnetic light and ...

Asymptotic analysis of dielectric coaxial fibers [PDF]

, 2002
Using an asymptotic analysis, we analytically calculate the dispersion and the field distribution of guided modes in an all-dielectric coaxial fiber. We compare the analytical results with those obtained from numerical calculations and find excellent ...

All-dielectric nanolaser

, 2014
We demonstrate theoretically that a subwavelength spherical dielectric nanoparticle coated with a gain shell forms a nanolaser. Lasing modes of such a nanolaser are associated with the Mie resonances of the nanoparticle. We establish a general condition for the lasing threshold and show that the use of high refractive index dielectric media allows for ...

All-dielectric resonant metasurfaces with a strong toroidal response

, 2018
We demonstrate how to create all-dielectric metasurfaces with a strong toroidal response by arranging two types of nanodisks into asymmetric quadrumer clusters.

Metasurface-Enabled Honey Encryption: A New Paradigm for Secure Data Transmission

IEEE Photonics Journal
Honey encryption is a potent data security method that thwarts attackers by generating deceptive yet plausible messages, but its large-scale adoption is hindered by cumbersome and time-intensive encryption processes, and this study aims to address this ...
