Effect of optical transmitter on EMP plane wave distribution

When electric field is measured, one kind of optical fiber measurement system is often used. And we are often concerned with the effect of the device on electromagnetic wave distribution. in this paper, the finite-difference time-domain (FDTD) method is used to model the effect of optical transmitter on EMP (electromagnetic pulse) plane wave distribution. From the numerical result, we find the law of the effect of optical transmitter on EMP plane wave distribution.
