Summary:
To perform magnetic near-field measurements with high accuracy in gigahertz frequency range, we are developing an optical magnetic field probe using an electrooptic crystal and a laser beam for signal transmission. Here we report the results of a FDTD (Finite Difference Time Domain) simulation of the frequency response characteristics of optical magnetic field probes up to 100 GHz and the invasiveness of the probes when measuring the electromagnetic field distribution above a microstrip line, The purpose is to verify the measurement accuracy and clarify design guidelines for optical magnetic filed probes.
