Abstract :
It is shown that an analysis of scattering from an open-ended waveguide cavity can be accomplished by time-frequency distribution (TFD) techniques. Three TFDs are used for scattering analysis of a circular waveguide cavity. Propagating modes and cutoff frequencies can readily be determined from the TFD, whereas neither time nor frequency representations will provide such information.<>
