Abstract : A method is derived for obtaining parameters which characterize higher order surface wave mode propagation on cylindrical columns with radially inhomogeneous permittivity bounded by a homogeneous medium. The method is well suited for application to boundary value problems where conventional Green's function techniques or expansions in series of known functions cannot be used since it works directly with the coefficients of a particular set of differential equations. The only theoretical restriction on the permittivity function is that it ust be non-singular. Numerical results were obtained for some permittivity models as a demonstration of the application of the method. (Author)
