Summary :

Cylindrical dielectric waveguide with a periodically varying radius are investigated numerically. The mode-matching method that matches the boundary conditions in the sense of least squares in applied to this problem, using the hybrid-modal representation. The accurate numerical results of the dispersion relations and field distribution are presented for the HE₁₁ mode. It is shown that the attenuation rate in the stopband is significantly smaller than that of TE₀₁ mode, whereas the HE₁₁ mode suffers an additional power leakage due to the coupling with EH₁₁ and HE₁₂ modes of radiation region.
