Abstract :
To determine the resonant fields of a dielectric resonator with high permittivity ¿r the asymptotic theory with 1/¿¿r as a small parameter, is extended with a correction term to yield accurate results even for relatively low values of ¿r. Data are shown for the lowest ¿-independent, "non-confined" mode of a ring resonator, which radiates as a magnetic dipole.
