Quasistatic Oscillations in Subwavelength Particles: Can One Observe Energy Eigenstates?

Abstract: In increasing the capabilities of the optical and microwave techniques further into the subwavelength regime, quasistatic resonant structures have attracted considerable interest. Electromagnetic responses of electrostatic (ES) plasmon resonances in optics and magnetostatic (MS) magnon resonances in microwaves give rise to a strong enhancement of local fields near the surfaces of subwavelength particles. In the near-field regions of subwavelength particles, one can measure only either the electric or magnetic … Show more

“…In Ref. [47] it was discussed that in a case of the surface plasmon resonances in subwavelength optical metallic structures no retardation processes characterized by the electric dipole-dipole interaction and described exclusively by electrostatic wave function ( . Such a behavior can be obtained in a ferrite particle in a form of a quasi-2D disk.…”

“…The MDMs in a ferrite disk are characterized by topologically distinct structures of the fields. Using electromagnetic boundary conditions, one obtains the following equation for a membrane wave function on a lateral surface of a ferrite disk of radius : [53,63,66,67] (̃) r= − − (̃) r= + = 0 (33)…”
