We develop a theoretical approach that makes it possible to analyze the role of multipole
contributions in the scattering spectra of arbitrarily shaped magnetic particles with the …

A review of natural materials that exhibit negative permittivity or permeability, including
gaseous plasma, metals, superconductors, and ferromagnetic materials, is presented. It is …

We report a thorough theoretical investigation of magnon-assisted photon transitions in
magnetic garnet micron-sized spheres, which operate as optomagnonic resonators. In this …

The authors extend the resonant modal theory (RMT) developed previously for a metal
object to an arbitrary source region consisting of metals, dielectrics, or a combination of both …

We employ the extended boundary condition method (EBCM) that we properly extend so as
to describe gyroelectric and gyromagnetic (ie, gyrotropic) anisotropy and report on the …

Two sets of irregularly placed dielectric nano‐spheres are synthesised as two nano‐
antennas. One of them has an end‐fire and the other has a pencil‐beam far‐field radiation …

A theoretical method is proposed and applied to design a nano-antenna consisting of a
number of dielectric spherical nano-particles to scatter the incident plane-wave in an …
