INTERACTION OF MODES IN A MICROWAVE CAVITY RESONATOR

Abstract

The quantum mechanical concept of zero-point energy has been utilised to  calculate the minimum energy differences between the desired and all the undesired  modes appearing in a cylindrical echo-box when the latter is excited at 9 Kmc to  operate in the TEo-1-2  mode. Expressions for the mutual energy and the coupling  coefficient between the two companion modes TE o -1-12  - TM 1-1 have been derived  with the help of the field equations. The paper ends with a discussion of the  significance of the total energy of a microwave cavity resonator.
