This paper introduces the structure of gigahertz TEM cell (GTEM cell). And the Finite-Difference Time-Domain (FDTD) method is used to model electromagnetic field of effective work space of GTEM cell accurately. The effect of meauring system put at the effective work space is also analyzed. This work will offer theory direction of electromagnetic field distribution of effective work space of GTEM cell.
When electric field is measured in the bounded-wave EMP simulator experiment, one kind of optical fiber measurement system is often used. At the same time, the effect of optical transmitter on electromagnetic wave distribution is often concerned. In this paper, we assume that the optical transmitter is placed on the working region of the bounded-wave EMP simulator and the Finite-Difference Time-Domain...
In this paper, we assume that the bounded-wave simulator is placed on the ground in the experiment. And the finite-difference time-domain (FDTD) method is used to model electromagnetic field at working region. From the numerical result, we can see that the ground has great effect on the electromagnetic wave.
