Multi-Channel, High Resolution, High Dynamic Range, Broadband RF Mapping System

ABSTRACT: In this SBIR project, EMAG Technologies Inc. proposes to develop a multi-channel real-time electric and magnetic field measurement system. The proposed system will utilize non-metallic optical probes with a very small footprint. As a result, such measurements will be non-invasive and will not perturb the fields of the device under test (DUT). In addition, the optical probes provide a very large bandwidth and a very high spatial resolution. The proposed probes also provide a very large dynamic range. The same probes can measure very low field values as well as extremely high field intensities with long standoff distances. Novel methods are proposed to extend both the bandwidth and the upper frequency limit of the measurement system. BENEFIT: The proposed field measurement system will enable RF designers and test & evaluation engineers to accurately quantify both desired and unintended effects of emitters and radiators on a variety of systems including electronic devices and human body.
