Abstract
We present novel electric and magnetic field measurement systems utilizing optical technologies, which have been developed, tested, and calibrated in the frequency region up to 2 GHz. They show an advantage over currently available measurement systems in that they are 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 (FDTD) algorithm for solving Maxwell's equations. Both probes were calibrated using a gigahertz transversal electric and magnetic cell, and the results show a linear response.
