A rectangular waveguide with transverse slots located periodically in the broad wall is analysed by the transverse resonance procedure. The slots are replaced by equivalent conductances and susceptances these are used in the resonance equation to obtain leaky and surface wave solutions. The theoretical solutions for the complex axial propagation constant are found, and these results are verified experimentally. The transverse resonance method of solution is shown to present advantages over previously derived results.
