Author Description

Excerpt from An Electromagnetic Evaluation of the Nasa Space Power Facility at Plum Brook Station <p>Sandusky, Ohio and is managed by the nasa John H. Glenn Research Center in Cleveland, Ohio. <p>This set of evaluation measurements and analysis were intended to quantify the electromagnetic characteristics of this chamber while empty. The experimental data that we collected include an extensive set of point-to-point signal-propagation and attenuation (insertion - loss) measurements, direct measurements of electric fields generated in the chamber by a high power radio frequency source, shielding effectiveness of the aluminum shell, and environmental ambient radio frequency signals. These measurements spanned the frequency spectrum from below 100 mhz to 40 ghz. We are able to estimate several important chamber characteristics by analyzing these data. These include attenuation, decay time, mode bandwidth, quality factor (q), electric field related to input power, and field uniformity. <p>About the Publisher <p>Forgotten Books publishes hundreds of thousands of rare and classic books.
