A Novel Vector Spatial Field Mapping Technique Using Electro-Optic Sampling

摘要

We propose a simple and novel technique for mapping vector spatial fields using electro-optic (EO) sampling. Our technique utilizes a sandwich-like EO crystal in which a dielectric mirror is inserted into the EO crystal. Three-dimensional field measurements at several given heights above a two-dimensional RF resonant structure were successfully demonstrated. Field scanning at any height is possible if the sandwich-like EO crystal is appropriately constructed.
