Abstract
Because of the complicated geometry of the slotted structure, analytical theories of such structures are inevitably developed on the basis of simplifying assumptions. On the other hand, the accuracy of the theory is of importance to the design of microwave interaction structures. In this study, modes of the slotted waveguide are investigated analytically and simulated with the HFSS code. It is shown that, in spite of the approximations made, the dispersion relation and field patterns of the standard analytical theory are in excellent agreement with the HFSS simulations over the complete range of the slot depth. Modes not built into the theory will also be noted. © Springer Science+Business Media, LLC 2006.
