✦ Synopsis

The method of contour lines in conjunction with the method of conformal mapping is used for the determination of cutoff frequencies of hollow waveguides with arbitrary boundary cross-sections. Calculations are presented .for acoustically soft waveguides. Examples of numerical evaluation are presented for a number of different cross-sections, some of which have not been discussed in the literature as yet.

## Abstract The cutoff frequencies of higher order modes in a symmetrical strip line are calculated using the variational finite‐element method combined with conformal mapping. Conformal mapping is used to improve the modeling of the infinite transverse extents of a strip line. Then the finite‐elem
