Abstract Starting from homogeneous scalar Helmholtz’s equations associated with Borgnis potential function in a cylindrical coordinate system, and based on the standing wave concept of slow-wave introduced in the paper, the analytic expressions of the dispersion relation for azimuthally symmetric transverse magnetic modes in the split cavity with three cavities are derived, by using boundary conditions for Borgnis potential function in conjunction with field matching conditions at the common interface between the adjacent subregions. Besides, the effect of the high frequency structure dimensions of split cavity with three cavities on its resonant frequency is analyzed in detail.
