A novel time-domain volume integral equation (TD-VIE) is proposed to analyze the transient electromagnetic scattering from inhomogeneous dispersive objects. In this TD-VIE method, the higher order Nyström method is applied in spatial domain. Namely, the curvilinear tetrahedron elements are utilized to discretize dielectric objects and resulting unknowns are volume electric current density. The Lagrange...
The parabolic equation (PE) method is derived from the wave equation, and it has been widely used to solve electromagnetic wave propagation problems. In recent years, it was realized that the PE method can also be applied to scattering problems. The PE method meets the demand for higher efficiency and accuracy at the same time when there are limited computational resources. In this paper, both co-polarized...
In this paper, microwave breakdown is analyzed in arbitrarily-shaped waveguide with the help of the Spectral Element Method (SEM). Both the electromagnetic fields distributed in the structure and the free electron continuity equation are solved by the SEM. Based on such a highly accurate numerical method, both tail-erosion phenomenon in time domain and bandwidth broaden in frequency domain caused...
A marching-on-in-degree (MOD) solution of the time-domain combined field integral equation (TD-CFIE) with Nystrom scheme is proposed to analyze transient electromagnetic scattering from arbitrarily shaped perfect electrically conducting (PEC) objects. In this scheme, the Lagrange interpolation polynomials and weighted Laguerre polynomials are used to represent the spatial and temporal basis functions,...
This paper is a study on the numerical solution of linear systems arising from the discretization of the improved electric field integral equation (IEFIE) for electromagnetic scattering problems. Using incomplete LU factorization preconditioner, the IEFIE is solved by generalized minimal residual iterative method in the context of the multilevel fast multipole algorithm (MLFMA). Numerical results...
