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

Metallically coated dielectric rectangle resonator
Applied Optics, 2015The double transfer matrix method (DTMM) is proposed for calculating the eigenvalues of the resonant mode of a metallically coated dielectric rectangle resonator. Two-dimensional electromagnetic analyses are performed to investigate the optical influences induced by planar structure parameters. The results show that there theoretically exists a highest

Accurate Resonant Frequencies of Dielectric Resonators
IEEE Transactions on Microwave Theory and Techniques, 1977The applications of dielectric resonators are currently of considerable interest in microwave integrated circuits. The design of a dielectric resonator depends on its natural resonant frequencies. Since exact solutions of dielectric rectangular and cylindrical resonators cannot be rigorously computed a new and more accurate method has been developed to

Resonances of a "Pillbox" Dielectric Resonator
1978 8th European Microwave Conference, 1978Resonant frequency, quality factor and field plots are discussed for a circular-cylindrical dielectric resonator. These quantities are calculated in the limit ?r ??. The method is a perturbation technique based on an expansion in the (small) parameter (1/??r).

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.
