摘要

确定了t矩阵法对散射几何限制的原因。给出了t矩阵法应用的正确性条件。证明了在零场条件下对积分方程进行数值求解时，特别是在使用t矩阵法时，必须考虑波场解析延拓的奇异性。通过数值算例说明了理论结果。

T-matrix method and singularities of analytical continuation of wave field

The reason of limitations on scatterer geometry imposed by T-matrix method is ascertained. The condition of correctness of T-matrix method application is given. It is shown that at numerical solution of integral equations on the basis of null field condition, in particular at using T-matrix method it is necessary to take into account singularities of analytical continuation of wave field. Theoretical results are illustrated by numerical examples.
