Abstract
Application of the incident/reflected wave boundary condition to the wave equation for a weakly irregular waveguide leads to a spectral domain analysis of the open cavity (Fig. 1) with a typical maximum-field spectrum shown in Fig. 2. Low Q value due to the diffraction loss and the consequent overlapping of neighboring modes are the two reasons for the broadening of resonant lines. The latter also lowers the spectral domain Q values relative to those based on the commonly employed time domain approach.
