CHARACTERISTICS OF AN ELLIPTICAL ELECTRO-MAGNETIC RESONANT CAVITY OPERATING IN THE TE111 MODE
Abstract
Formulae are derived for the quality factor and resonant wave length of an elliptical resonant cavity operating in the TE sub 111 mode. Calculations are made and curves plotted for their variation with change in eccentricity for values of eccentricity less than 0.5. The necessary integrations are numerical using simplifying assumptions. For both the even and odd modes, the quality factor increased slightly as the eccentricity was increased from zero to a small value. A further increase in the eccentricity causes the quality factor for the even mode to decrease. The range of eccentricity (0 to 0.5) used was not sufficient to show the anticipated decrease for the odd mode. The eccentricity range considered was limited by the approximations used in the method of evaluation. The approximations were considered as fully justified for eccentricities less than 0.4 and subject to some error for eccentricities between 0.4 and 0.5.
