摘要

将裂纹建模为指定电偶极子分布的数学曲面，用小参数法将电磁场在圆形裂纹上的散射问题归纳为牛顿势型超奇异积分方程组。针对这一问题，提出了二元正交多项式法。证明了裂纹偶极子等效矩与外低频电场法向分量的正比关系。

Low-frequency electromagnetic scattering on the circular crack in a conductive body

Modelling the crack as mathematical surface on which specified some distribution of electrical dipoles and using the method of small parameter the problem of scattering of the electromagnetic field on the circular crack adducted to system of the hypersingular integral equations of the Newtonian potential type. For the solution the method of orthogonal polynomials of two variables was proposed. Demonstrated that value of equivalent moment of dipole of the crack proportionate to normal component of the external low-frequency electric field.
