Gh. Peng et Jf. Lee, ANALYSIS OF BIAXIALLY ANISOTROPIC WAVE-GUIDES USING TANGENTIAL VECTORFINITE-ELEMENTS, Microwave and optical technology letters, 9(3), 1995, pp. 156-162
Problems of biaxially anisotropic waveguides with arbitrary cross sect
ion are formulated in terms of vector and scalar potentials. By using
the tangential vector finite elements, electromagnetic characteristics
of propagating modes in the waveguides are obtained without the occur
rence of any spurious modes. Numerical results are verified and agreem
ents with other published results are achieved. (C) 1995 John Wiley &
