文摘
- •
Spherical dielectric resonators have a continuous spectrum of resonant frequencies.
- •
A pair of outward-inward traveling waves forms the mode field outside the sphere.
- •
Mode field of near-zero normalized frequencies is concentrated outside the sphere.
- •
The quality factor due to radiation degrades by increasing the dielectric loss.
