Solving Maxwell equations in 3D prismatic domains

In this Note, we introduce the Fourier Singular Complement Method, for solving Maxwell equations in a 3D prismatic domain. The numerical implementation of this method provides a continuous approximation of the electromagnetic field. It can be applied to the computation of propagating and evanescent modes in prismatic stub filters, thus generalizing 2D approaches. To cite this article: P. Ciarlet, Jr., et al., C. R. Acad. Sci.
