摘要
为了克服用 IPO法处理电大尺寸形状相对复杂的腔体散射时会出现迭代收敛慢甚至发散现象 ,本文引入松弛因子、异步迭代以及继承迭代等措施改进迭代的收敛性 。
It is found that the convergence becomes worse, when the iterative physical optic (IPO) method is applied to the computation for electromagnetic scattering of a complex large open ended cavity. To overcome this difficulty, some modifications, such as the under relaxation iterative method, succession iterative method, and Gauss Seidel iterative method are introduced to the commonly used IPO scheme. Examples are given to demonstrate the availability of presented modifications.
