According to the coupled-wave equations, the irregular properties at boundaries of the wave-guide with helical corrugation is analyzed using the method of impedonce perturbation. The general coupled equation of the helical wave-guide and the formuale for coupled coefficient are obtained. Based on rules of mode coupling in helical wave-guide, the dispersion equation is obtained and the dispersion characteristics are discussed.
