Summary: 
A vectorial finite-element method for the analysis of three-dimensional dielectric waveguides is developed in terms of all three components (Hx, Hy, and Hz) of the magnetic field H. In this approach, the divergence relation for H is satisfied and the spurious, nonphysical modes which are included in the solutions of the earlier vectorial finite-element methods do not appear. In order to verify the accuracy of the method, the numerical results for a rectangular waveguide half-filled with dielectric are presented and compared with the exact results. The dielectric rectangular waveguides are also analyzed.
