## Abstract 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,
