Radiation mode composition of open resonators in the form of axisymmetric, weakly irregular waveguides

Reduction of spurious wave conversion in irregular sections of an opencylindrical resonator is studied. The relative power level of extraneous waves at the output of a resonator with a sinusoidally varying radius is considered. It is shown that improvement in radiation purity is possible through opt...

Zusammenfassung:Reduction of spurious wave conversion in irregular sections of an opencylindrical resonator is studied. The relative power level of extraneous waves at the output of a resonator with a sinusoidally varying radius is considered. It is shown that improvement in radiation purity is possible through optimization of the output waveguide junction profile.
