The mixed-edge dement whie is developed in recent years is an effective method for eliminating the spurious solutions. In this paper
a systematic construction method of the triangular mixed-edge element is proposed. As examples
explicit formulations of the interpolation functions for one- and two-order triangular mixed edge dements are given. The calculations of the dispersion curves for several guiding structures verify that the proposed mixed-edge element not only eliminates the spurious solutions
but also has higher computing efficiency. The comparison between two mixed-edge elements shows that the accuracy and convergence of the low-order mixed-edge element are clearly improved by using the high-order one.
