Abstract

The calculation results of the mutual coupling coefficients of different relative sizes cylindrical dielectric resonators with magnetic modes are presented. A general formula for the mutual coupling coefficients for an arbitrary orientation of the cylindrical DRs in the open space are obtained. The basic patterns of coupling coefficient changing with the variation of the relative position of the resonators are examined.

Highlights

  • Cylindrical DRs are applying today in various microwave devices [1 - 6]

  • The coupling coefficients of the Cylindrical DRs did not studied in full measure even in case of the lowest modes

  • The fields and frequencies of the DR oscillations are defined by values of the mutual coupling coefficients

Summary

Coupling coefficient calculating

Allocation microresonators side by side with each other leads to the coupling oscillations appearance. The fields and frequencies of the DR oscillations are defined by values of the mutual coupling coefficients. The coupling coefficient can be determined as a surface integral [9]: sn. Expressed via the eigenmode field (es,h s ) of one (s -th) DR on the surface of another ( n -th) DR. S,n 1,2 ; and n - is the normal to the surface sn of n -th DR, 0 - is the resonance frequency of the resonators; wn - is the energy, stored in the dielectric
