In the context of the numerical simulation of seismic wave propagation , the perfectly matched layer (PML) absorbing boundary condition has proven to be efficient to absorb surface waves as well as body waves with non grazing incidence. But unfortunately the classical discrete PML generates spurious modes traveling and growing along the absorbing layers in(More)
Unsplit convolutional perfectly matched layers (CPML) for the velocity and stress formulation of the seismic wave equation are classically computed based on a second-order finite-difference time scheme. However it is often of interest to increase the order of the time-stepping scheme in order to increase the accuracy of the algorithm. This is important for(More)

A SPICE lumped circuit subcell model is formulated within the discontinuous Galerkin finite-element time-domain (DGFETD) discretization of Maxwell's equations. A fourth-order exponential time difference (ETD) algorithm is used for circuits that lead to stiff systems. The ETD method reduces to a standard fourth-order Runge-Kutta (RK4) time-integration for(More)
An efficient means of evaluating reactions arising from the mixed-potential integral equation for layered media for quasi-3D microwave circuits is presented. Analytical formulations for the z-integration in the spectral domain are derived, thus avoiding expensive 2D evaluation and interpolation of the layered Green's function. In this paper, closed-form(More)
