In this article, we consider the propagation problem inside a waveguide filled with a homogeneous bi-isotropic material. The cross section of the waveguide is assumed arbitrary. By using the classical theory for the 2D Helmholtz equation in the cross section and the null-field approach, we obtain the dispersion equation in an implicit form. The final equation is a potential candidate for the solution of the direct and the inverse propagation problems.
