Optically resonant dielectric nanostructures

Science, 2016
A 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., 2003
Experiments 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 ...
