The effects of birefringence and total internal reflection on the performance of current sensors that use the Faraday effect have been modeled numerically. The results show that, when these effects are present, the output electric field azimuth is affected by the position of the current-carrying conductor. In sensors that use highly circular birefringent fibers, however, the output azimuth is not affected.
