Excerpt from Design and Calibration of the Nbs Isotropic Electric-Field Monitor (Efm-5), 0. 2 to 1000 Mhz
Ah investigation was performed at nbs to find a device or phenomenon that could provide a useful sensor of EM fields of complicated structure. Most of the early attempts revealed severe limitations for designing a general-purpose probe. For example, thermal ri sensors based on absorbed heat energy or temperature rise in a lossy material could not be made sufficiently rugged and stable unless the response time was excessive. It was concluded early in the program that the preferred type of rf sensor consists of a short dipole antenna and semiconductor detector, which has a fast response time and good sensitivity.

Paperback. Etat : New. Print on Demand. This book details the design, calibration, and performance testing of a newly developed broadband radiation monitor, the EFM-S, for measuring electric field intensity in the radio frequency range. It discusses the theoretical determination of the most suitable field parameters for quantifying electromagnetic fields, as well as the design and fabrication of competitive types of measuring instruments. The EFM-S represents the culmination of the author's work on the project, meeting the design goals of accuracy, measurement range, isotropic response, wide frequency range, and portability. The EFM-S has nearly perfect isotropy over a 60 dB dynamic range. It can be used to monitor either weak plane-wave fields in the far zone of a transmitting antenna or the complicated fields only 5 cm from an rf leakage source. Its design and calibration will be of interest to those concerned with the design and use of field intensity meters and the measurement of electromagnetic fields.
