摘要：

This letter presents a new approach for finite-element time-domain electromagnetic analysis. The new method combines the property of high-order approximation in the time domain with the crucial property of unconditional stability. The proposed method has been used in circuit simulation and relies on employing a specific formulation of the numerical inversion of the Laplace transform. The method is validated using one- and two-dimensional scattering from a dielectric object.
