Embodiment Construction
[0053] The specific implementation process of the present invention can be divided into the following steps (such as figure 1 shown).
[0054] ①. According to the needs of practical problems, discrete spatial grids, selected basis function translation and scale factors, produce time-domain AH basis functions.
[0055] ②. The five-diagonal coefficient matrix on the left side of the implicit equation (13) and the non-zero items on the right side are composed of space grid division, medium parameters, initial conditions and excitation sources.
[0056] ③. The coefficient matrix is decomposed by LU, and the magnetic field coefficient in the AH domain is solved by the chasing method.
[0057] ④. Substitute the magnetic field coefficient into equations (10)-(11) to solve the electric field coefficient in the AH domain.
[0058] ⑤. Reconstruction of time domain electromagnetic field results using AH domain coefficients and basis functions.
[0059] The present invention wil...
