摘要：
An automatic procedure for the analysis of two-dimensional fast transient electromagnetic fields is presented. The fields are analyzed in the frequency domain by means of a node-based finite element procedure and the transients are derived by the application of Fourier transforms. The FEM mesh is generated through an algorithm which selects the element size as a function of the wavelength. The conductive regions are automatically removed from the FEM region when the value of the penetration depth is very small, and impedance boundary conditions (IBC) or perfect electric conductor (PEC) approximations are imposed. Open boundary conditions are applied at a distance varying with the frequency where the mesh is truncated. The FEM implementation of the proposed procedure is discussed.
