A technique is presented for determining the field in a series of cascaded, axisymmetric cylindrical cavities excited by a φ-independent source. The constituent cavities are either coaxial or circular-cylindrical. The field in each cavity is expressed in terms of the electric field in the apertures at the interfaces where adjacent cavities join. Coupled integral equations are formulated in the frequency domain from which these aperture fields are computed. From knowledge of the aperture fields, the complete field in the cavity structure can be determined. The frequency-domain data are used to compute the time-domain field in the system of cavities. Cavities were constructed and experiments performed to corroborate the computed data.
