Abstract
For the problem of conductivity parameter inversion in the Maxwell equation, It constructs a regularization-conjugate gradient inversion algorithm with a widely convergence. The widely convergent numerical algorithm which can solve the inversion problem of Maxwell equation is gained by organically combining the Homotopy method with global convergence for solving the nonlinear problems, and the conjugate gradient algorithm for solving the large-scale optimization problems with the regularization method Tikhonov for solving the ill-posed problems. The constructed algorithm is used to solve the inverse problem of conductivity parameter and solves the puzzle that the solution falls into the local minimal value in the solving process. The experimental result shows that the algorithm is effective, and can be applied in the parameter identification problems of other types.关键词
