| Abstract: | In the weakly guiding analysis of cutoff frequencies of elliptical waveguides, the advantages of the proposed elliptical Fourier series expansion method including generality, accuracy, efficiency and simplicity are demonstrated through detailed comparisons with the rigorous Mathieu function method, the finite element method, various important techniques and Dyott′s meansurement on practicle fibers. |
