| Abstract(in English) | To estimate the possibility of low frequency electromagnetic near-field calculation by FDTD method, the influences of the distance from radiation model to absorbing boundary are discussed, by the comparison of theoretical and simulated electrical field for the half wave dipole antenna put in the smaller analytical space than the wavelength. Comparison of the electric near-field strength calculated by FDTD and the theoretical value for PML's and Mur's ABCs, and influence of the number of calculation step (i. e. long time calculation ) are discussed. In the case of PML, it was confirmed that the calculated electric field strength has constant when the distance between the radiation source and the absorbing boundary is in the near-field, even at 0.07λ. For Mur's, the error is increased as nearing the desistance to less than λ/2. PML can be used when the distance from the analysis model to the absorbing boundary is less than λ/2. It is also resulted that there is almost no effect on the long time calculation, because the results up to 800,000 time step calculation with PML's and Mur's ABCs are both consistent. |
