Abstract :
We present a novel EM field measurement system utilising optical technology which has been developed, tested and calibrated in the frequency region up to 1.8 GHz. It shows an advantage over currently available measurement systems in that it is passive, all-dielectric and EM immune. A detailed analysis of field perturbation by the measuring probes in the near field region was performed using finite-difference time-domain algorithm. Both probes were calibrated using gigahertz transversal electric and magnetic cell, and the results obtained show a linear response
