On the study of the resonant properties of a biconical cavity with a dielectric rod using the quasiregular approximation method

摘要

The eigenfrequencies of a truncated biconical cavity with a dielectric cylinder are calculated as a function of the dielectric permittivity of the cylinder and the cone angles. The results of analytical calculation by the quasiregular approximation method are compared with the numerical results obtained using the classical scheme of the finite-element method. The range of cone angles in which the quasiregular approximation method is applicable is reported.
