A Theory of Mutual Impedances and Multiple Reflections in an N-Element Array Environment

Description: Abstract: A general theoretical approach is formulated to describe the complex electromagnetic environment of an N-element array. The theory reveals the element-to-element interactions and multiple reflections within the array. From the formulation, it is found that the interaction between an excited element and an open-circuited element can be viewed as the sum of terms describing all possible signal paths within the array environment which start from the radiating element and terminate on the… more

An Error Analysis for the Use of Presently Available Lunar Radio Flux Data in Broadbeam Antenna-System Measurements

Description: From introduction: Simple, precise expressions for lunar diameter, average brightness temperature, flux density, and shape factor are presented. An analysis of the relationship between these parameters and corresponding errors are included. For broadbeam (HPBW>d) antennas, results show that flux density and shape factor can be determined with errors less than 13 percent and 0.4 percent respectively at frequencies below 10 GHz. Extension of the analysis to higher frequencies is indicated.

Theory of Near-Field Phased Arrays for Electromagnetic Susceptibility Testing

Description: From introduction: The feasibility of using a near-field array for electromagnetic susceptibility testing is studied. The basic objective is to control the element weightings such that a plane wave is generated within the test volume. The basic theory is developed for arbitrary array geometries, and numerical results are obtained for finite planar arrays. A general near-field array synthesis technique is developed, and the technique minimizes the mean square error in the test volume while const… more

[Wyoming Uranium Evaluation] Volume 1: A Summary of the Geology and Uranium Potential of Precambrian Conglomerates in Southeastern Wyoming

Description: From deposit: Since 1975 a cooperative effort between the United States Department of Energy, United States Geological Survey, Geological Survey of Wyoming, the Geology Department, University of Wyoming, and various industry groups has resulted in the discovery of a series of uraniumthorium-and gold-bearing conglomerates in Late Archean and Early Proterozoic metasedimentary rocks of southern Wyoming. The mineral deposits were found by applying the time and strata bound model for the origin of u… more

Portland 1° x 2° NTMS Area, Maine and New Hampshire: Data Release

Description: From abstract: This data release presents preliminary results of ground water, stream sediment, and stream water reconnaissance in the National Topographic Map Series (NTMS) Portland 10 x 20 quadrangle. Stream sediment and stream water samples were collected from small streams at 1094 sites for a nominal density of one site per 13 square kilometers (five square miles) in rural areas. Ground water samples were collected at 560 sites for a nominal density of one site per 26 square kilometers (ten… more

Uranium Hydrogeochemical and Stream Sediment Reconnaissance in Southwestern Montana

Description: From introduction: This report presents data gathered in a Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) conducted by the Los Alamos Scientific Laboratory (LASL) in southwestern Montana. The HSSR was initiated by the US Department of Energy (DOE) to outline areas favorable for uranium exploration by examining uranium concentrations in natural waters and stream sediments.

Investigation of Alaska's Uranium Potential

Description: From addendum: Two types of analyses for uranium in the stream-sediment samples are presented. One split of the stream-sediment samples was sent to Resource Associates of Alaska's laboratory, where they were analyzed for U by the fluormetric method after acid extraction. This is the method employed for U by most laboratories. The completeness of uranium extraction unavoidably varies with the particular type of uranium-bearing minerals present and possibly with the amount of iron, manganese, and… more
