RT info:eu-repo/semantics/article T1 Analysis of Homogeneous Waveguides via the Meshless Radial Basis Function-Generated-Finite-Difference Method A1 Pereda, José A A1 Grande Sáez, Ana María K1 Meshless methods K1 Meshless methods Radial basis function generatedfinite difference method K1 Homogeneous waveguides K1 Cutoff wavenumbers AB The radial basis function generatedfinite difference (RBFFD) method is applied to the analysis of homogenous waveguides. To this end, the Helmholtz equation and the boundary conditions are collocated on the waveguide cross section. At each collocation node, derivatives are locally approximated by RBFFD formulas based on polyharmonic splines supplemented with highdegree polynomials. As a result, a sparse matrix eigenvalue problem is obtained which allows cutoff wavenumbers and axial fields to be calculated. To illustrate the accuracy of the method, we consider a semicircular and an eccentric circular waveguides.
