Abstract
We propose a new type of optical probe designed to detect magnetic near-fields with high accuracy up to the gigahertz range. The probe head consists of a loop antenna element doubly-loaded with electro-optic crystals. It optically realizes the operation of a conventional doubly-loaded loop probe and requires no metallic cables or hybrid junction. We examined the probe characteristics for magnetic field detection up to 10 GHz. We confirmed that the probe can detect magnetic fields near a microstrip line and suppress the influence of electric fields
