Calculation of the Electromagnetic Field in a Strip Line Using FDTD Method 2004-01-1706

Recently, study of electromagnetic compatibility (EMC) for vehicles has become more and more important. In this paper, the authors examine the potential effectiveness of the finite difference time domain (FDTD) method, one method for simulating an electromagnetic field, as a tool to analyze automotive EMC. The authors have calculated the electromagnetic field for a strip line, and examined the effectiveness of the calculation method by comparing the calculations with measurements. Consequently, the calculated trends of the spacial distribution of the electrical field surrounding the strip line are approximately equal to the measured trends. The calculations of the S-parameter are very close to the measurements in the 20 to 200 MHz frequency range.
