Based on multiresolution analysis,a method for computation of TE and TM modes in arbitrary cross sections is described.The method uses expansion in terms of scaling functions to approximate the axial field component (Ez or Hz) and transforms the field equation into a matrix equation by applying a variational formulation.The matrix elements are formulated by dividing the waveguide cross section into rectangles and using third-order B-spline.Numerical examples are provided for various waveguides to show the validity and effectiveness of the method.
