A parallelizable unconditional stable discontinuous Galerkin finite element time-domain (DG-FETD) method is presented in the paper. The Crank-Nicolson (CN) scheme is implemented in DG-FETD method and it can eliminate the stability constraint from the minimum size of meshes. A causal domain decomposition technique is proposed to make the coupled system parallelizable. A numerical example is simulated...
The alternating direction implicit (ADI) scheme is used for the parabolic equation (PE) method to analyse electromagnetic scattering problems. The three-dimensional (3D) electromagnetic scattering problem can be reduced to a series of 1D problems to be solved by the ADI-PE method, which is more efficient than the traditional Crank-Nicolson scheme. In this way, both the memory requirement and the central...
