The use of rectangular and triangular basis functions in the method of moments to analyze the problem of scattering of electromag-( ) netic wa¨es by dielectric objects with high dielectric constant ) 10 r leads to con¨ergence problems due to the spurious charges associated with the basis functions.
## Abstract The cutoff wavelengths of elliptical waveguides are calculated by using a meshless collocation method with the radial basis functions, which only needs point sampling, and no mesh discretization is performed. The field value at any point inside the waveguide can be obtained by interpola
The solenoidal basis functions defined on tetrahedrons are modified to permit the analysis of the problem of scattering of electromagnetic wa¨es by inhomogeneous dielectric objects. In the analysis of the scattering of EM plane wa¨es by an inhomogeneous dielectric cube, we compare our results with t
