Abstract:

© 2002-2011 IEEE. In this letter, nonorthogonal locally 1-D finite-difference time domain based on fundamental scheme (F-LOD-NFDTD) is presented for analyzing electromagnetic curved structures. The formulation based on fundamental scheme with curvilinear coordinate is performed in convenient matrix-operator-free forms in the right-hand side of resultant equations. The convolutional perfectly matched layer absorbing boundary condition is also incorporated. The nonorthogonal grids are used to fully mesh the computational domain that leads to efficient computation. A comparison to the conventional LOD-NFDTD in terms of CPU time and memory requirements reveals the merits of the proposed F-LOD-NFDTD method in terms of lighter calculation burden and higher efficiency. Numerical results are presented to illustrate the significance of the proposed approach.
