Intercavity coupling constant of the cavities

Resumo

The coupling coefficient of two cavity resonators taking very small values is considered. A technique for measuring the coupling coefficient via loaded Q factors and coefficients of coupling with external lines is proposed. The dependence of the intercavity coupling coefficient on dimensions of the aperture of the diaphragm between the cavities is determined. The data obtained are compared with the values obtained using a technique based on finding the system resonance frequencies corresponding to phase angles 0 and π of intercavity oscillations.
