摘要：

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