New type of electric-field probe with optical fibers

Abstract

This paper reports a new type of isotropic broadband(1MHz-2GHz) electric field probe that we have developed recently. This kind of probe takes optical fiber as the signal transmission line , so it is very capable of resisting electromagnetic interference. Its operation principle and main performances are described in detail. The corresponding measurement results are presented. In addition , its capability for resisting electromagnetic interference is also investigated.
