In this paper, an introduction to electromagnetic scattering is presented. We introduce the basic concepts needed to face a scattering problem, including the scattering, absorption, and extinction cross sections. We define the vector harmonics and we present some of their properties. Finally, we tackle the two canonical problems of the scattering by an infinitely long circular cylinder, and by a sphere, showing that the introduction of the vector wave function makes the imposition and solution of the boundary conditions particularly simple.
本文介绍了电磁散射。我们介绍了处理散射问题所需的基本概念，包括散射、吸收和消光截面。我们定义了矢量谐波并介绍了它们的一些性质。最后，我们解决了由无限长圆柱体和球体散射的两个典型问题，表明矢量波函数的引入使得边界条件的施加和求解特别简单。
