The article presents an overview of the state of the art of (mode) matching (MM) methods applied for the rigorous, fast CAD and optimization of waveguide components, and describes some recent advances. The great technical importance of the MM technique is its extremely high computational efficiency achieving complete full‐wave analyses of typical waveguide components several orders of magnitude faster than electromagnetics (EM)‐based methods applying space discretization techniques. Hence, the MM technique allows advantageously the direct EM‐based optimization of waveguide components toward given specifications within shortest response times. Adequate extensions of the MM technique, such as the boundary contour MM (BCMM) method or hybrid combinations with other EM methods such as the finite‐element method, allow extended flexibility. Typical application examples will illustrate the versatility of the MM methods.

Microwave components/systems that meet the tight requirements of advanced applications—in particular concerning reduced mass and size, increased specs and performance, minimized design time, and cost—demand fast EM‐based CAD tools yielding accurate, optimized designs within adequately short response times. This goal makes flexible hybrid solutions desirable, which typically go beyond the efficiency possibilities of single methods. The article presents an overview of the state of the art of hybrid CAD mode‐matching (MM)/finite‐element (FE)/method‐of‐moments (MoM)/finite‐difference (FD) techniques applied for the rigorous, fast CAD and optimization of waveguide components and aperture antennas, and describes some more recent advances. The hybrid techniques presented combine advantageously the efficiency of the MM method with the flexibility of FE, MoM, and FD methods. Typical application examples illustrate the versatility of these techniques; the accuracy is demonstrated by comparisons with available measurements.
