Optically resonant dielectric nanostructures
Science, 2016A clear approach to nanophotonics The resonant modes of plasmonic nanoparticle structures made of gold or silver endow them with an ability to manipulate light at the nanoscale. However, owing to the high light losses caused by metals at optical wavelengths, only a small fraction of plasmonics applications have been realized ...

Temperature sensitivity of dielectric resonators and dielectric resonator oscillators
Proceedings of the 42nd Annual Frequency Control Symposium, 1988., 2003Experiments were performed on L-band and S-band dielectric resonators (DRs) and direct-resonator-based oscillators (DROs) to investigate the details of their behavior with variation in temperature. Measurements were performed using commercially available Zr/Sn titanate and barium tetratitanate dielectric resonator materials enclosed in metal cavities ...

Resonant frequency of dielectric resonator
Proceedings RAWCON 98. 1998 IEEE Radio and Wireless Conference (Cat. No.98EX194), 2002In this paper, an effective dielectric constant (EDC) has been introduced in an axial attenuation constant of dielectric waveguide model (DWM) method to calculate more accurately the resonant frequency of the TE/sub 01/spl delta// mode of a dielectric resonator (DR) in an MIC environment.

Resonant Behavior of Dielectric Objects (Electrostatic Resonances)
Physical Review Letters, 2003Resonant behavior of dielectric objects occurs at certain frequencies for which the object permittivity is negative and the free-space wavelength is large in comparison with the object dimensions. Unique physical features of these resonances are studied and a novel technique for the calculation of resonance values of permittivity, and hence resonance ...

2015 Conference on Microwave Techniques (COMITE), 2015
This article is focused on using a dielectric resonator as a radiating element of a antenna with the aim to reduce dimensions of such antennas compared to classical microstrip antennas. Such antenna was build and its parameters tested in frequency band of 2.9 to 3.1 GHz.

Journal of Applied Physics, 1939
We show that suitably shaped objects made of a dielectric material can function as electrical resonators for high frequency oscillations. We develop the theory of such resonators very briefly and compute their resonant frequencies and losses in some very simple cases. The paper concludes with an observation on the behavior of dielectric wave guides.

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.

Nanoscale TiO_2 dielectric resonator absorbers
Optics Letters, 2016We demonstrate a narrow-band plasmonic absorber based on a uniform array of nanoscale cylindrical dielectric resonators (DRs) on a metallic substrate at visible frequencies. Under a normally incident plane-wave excitation, the DRs resonate in their horizontal magnetic dipolar mode, which can be seen as localized plasmonic hot spots.

Nonlinear Fano-Resonant Dielectric Metasurfaces
Nano Letters, 2015Strong nonlinear light-matter interaction is highly sought-after for a variety of applications including lasing and all-optical light modulation. Recently, resonant plasmonic structures have been considered promising candidates for enhancing nonlinear optical processes due to their ability to greatly enhance the optical near-field; however, their small
