Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index

open access: yesAdvanced Photonics Research, EarlyView.
Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.

Vortices and chirality of magnetostatic modes in quasi-2D ferrite disk particles

open access: yes, 2007
In this paper we show that the vortex states can be created not only in magnetically soft "small" (with the dipolar and exchange energy competition) cylindrical dots, but also in magnetically saturated "big" (when the exchange is neglected) cylindrical ...
