Analyses of spherical functions-based numerical dispersion relation are performed for the finite-difference timedomain method in spherical coordinates. Errors in the numerically rendered wavenumber due to finite mesh densities are analyzed as a function of absolute position within the spherical mesh, solutions mode orders and mesh density.
