Flexible dielectric waveguides with powder cores [PDF]
, 1988 Flexible dielectric waveguides have been demonstrated at 10 GHz and 94 GHz using thin-wall polymer tubing filled with low-loss, high-dielectric-constant powders. Absorptive losses of the order of 10 dB/m were measured at 94 GHz.

Semicylindrical microresonator: excitation, modal structure, and Q factor
, 2020 The semicylindrical microresonator with relatively simple excitation with a plane wave is studied. The resonator is formed on the base of the dielectric/metal/dielectric structure, where the wave energy penetrates into resonator through a thin metal ...

Magnetic field tuning of polaron losses in Fe doped BaTiO3 single crystals
, 2012 Artificial tuning of dielectric parameters can result from interface conductivity in polycrystalline materials. In ferroelectric single crystals, it was already shown that ferroelectric domain walls can be the source of such artificial coupling.

Full-wave electromagnetic modes and hybridization in nanoparticle dimers [PDF]
, 2019 The plasmon hybridization theory is based on a quasi-electrostatic approximation of the Maxwell's equations. It does not take into account magnetic interactions, retardation effects, and radiation losses. Magnetic interactions play a dominant role in the
