Dielectric resonant metaphotonics
Photonic and Phononic Properties of Engineered Nanostructures XI, 2021Recent rapid progress in subwavelength optics and nanophotonics with dielectric structures is underpinned by the physics of Mie resonances excited in nanoparticles with a high refractive index, and...

The dielectric resonator antenna
1985 Tenth International Conference on Infrared and Millimeter Waves, 1985There is, today, strong interest on the part of both military and commercial users, in antenna systems which can operate efficiently in the millimeter wave region (100–300 GHz) and above. Reducing the size of currently-used microwave frequency antennas to obtain higher resonant frequencies will usually be unsuccessful, either because the small size ...

IEEE Transactions on Microwave Theory and Techniques, 2005
This paper discusses the possibility of constructing a resonant element from dielectric material shaped into a helix. The modeling conducted shows that the mode associated with ceramic quarter-wave resonators is present within a coiled dielectric helix, the properties of which are strongly dependent upon the pitch and the thickness of the coils.

The Dielectric Microwave Resonator
Proceedings of the IRE, 1962Pieces of single crystals of rutile show high Q resonances in the microwave range. A piece about (1/7?)3 has a Q as high as that of a metal-walled cavity at room temperature. Lowering the temperature increases both the Q and the resonant wavelength. Q's of 105 were seen at 4°K.

2004 14th International Crimean Conference "Microwave and Telecommunication Technology" (IEEE Cat. No.04EX843), 2004
The problem of scattering electromagnetic waves from a radiating aperture by a system of high-Q dielectric resonators (DR) in free space is considered. General expressions are presented for calculating both the amplitudes of coupled oscillations and also the scattered field in the wave zone of the resonator system.

Dielectric Waveguides and Resonators
1998We have seen in the last chapter that, for single-mode operation, the dimensions of waveguides and cavities must be of the same order as the operating wavelength. The reasonable dimensions for metal work are in centimeter and millimeter range. For this reason, metallic waveguides and cavity resonators including coaxial lines and coaxial cavities are ...
