摘要

The Gandhi's scaled-frequency FDTD (finite-difference time domain) method for electromagnetic fields of low frequency was modified, and so can be adaptable to the numerical computation of electromagnetic phenomena in metals. The computational results by a simplified model agreed well with the analytical solu- tions. A new treatment for the interface of metal and dielectric was also presented, further how and why it is was explained. The low-frequency electromagnetic fields were computed successfully due to this treat- ment. The computational results are in excellent agreement with the experimental ones.
