摘要
通过计算和测量研究了GHz横电磁波传输室内场分布的特点.介绍了利用三维FDTD法计算GHz横电磁波传输室内场分布的方法、需要注意和解决的一些问题,并将理论结果与实验结果进行了比较,符合得比较好.可以看出在GHz横电磁波传输室的有效工作区内场强的变化小于4dB,可以满足电磁兼容测量的要求.
The field distribution in the GTEM Cell(1GHz transverse electromagnetic transmission Cell) is discussed. The field distribution in the GTEM Cell is theoretically computed by the 3D FDTD method and is experimentally measured. The process for calculating field distribution in the GTEM Cell by the 3D FDTD means with a number of problems is introduced in detail. Theoretical results agree well with experimental data. It is proved that the variations of the field in the effective region of a GTEM Cell are less than (4dB), which can satisfy the requirements for the measurement of electromagnetic compatibility.
