Nonlinear Excitation of Ideal Anapoles
Radoslaw Kolkowski, Matti Kaivola, Andriy Shevchenko
Optical anapoles have attracted significant interest as a promising platform for enhancing light-matter interactions at the nanoscale. An ideal anapole is a localized excitation of…
Calculating the electromagnetic characteristics of bifacial optical nanomaterials
P. Grahn, A. Shevchenko, M. Kaivola
We introduce a formalism that describes the interaction of light with bifacial optical nanomaterials. They are artificial noncentrosymmetric materials in which counter-propagating…
Interferometric description of optical metamaterials
P. Grahn, A. Shevchenko, M. Kaivola
We introduce a simple theoretical model that describes the interaction of light with optical metamaterials in terms of interfering optical plane waves. In this model, a metamateria…
Electromagnetic multipole theory for optical nanomaterials
P. Grahn, A. Shevchenko, M. Kaivola
Optical properties of natural or designed materials are determined by the electromagnetic multipole moments that light can excite in the constituent particles. In this work we pres…
Electric dipole-free interaction of visible light with silver metadimers
P. Grahn, A. Shevchenko, M. Kaivola
In subwavelength-sized particles, light-induced multipole moments of orders higher than the electric dipole are usually negligibly small, which allows for the light-matter interact…
Electromagnetic force density in dissipative isotropic media
Andriy Shevchenko, Matti Kaivola
We derive an expression for the macroscopic force density that a narrow-band electromagnetic field imposes on a dissipative isotropic medium. The result is obtained by averaging th…
