Abstract :
The cutoff wavenumbers knm of the surface wavemodes in a Goubau line are determined by a procedure that leads directly to the eigenvalue equation in the limit of zero values for the wavenumber of the infinite exterior medium. The same result has been obtained by a much longer procedure based on an extension of previous methods used in correction with simple dielectric waveguides. Numerical results and related curves for all types of modes are also included.
