Transmission eigenvalue problem arose in inverse scattering theory and received significant attention recently. In this talk, we first write the problem as a non-selfadjoint fourth order problem. Then we show that the transmission eigenvalue can be obtained by solving a series of self-adjoint fourth order problems which is discretized by the Argyris elements. Then we propose an iterative method to compute transmission eigenvalues. Numerical examples show the viability of the proposed method. We also discuss a mixed finite element method for the transmission eigenvalues.
