Abstract : Additions were made to the data base with emphasis on Antennas and Propagation; moreover, these additions and those made during Phase IV in its entirety were scanned for assignment to nine categories of interest to the Electromagnetic Systems Division in its Microfiche Dissemination Program. The pertinent literature references accompanying these categorized EMPIRE documents were prepared in standardized format for microfiche input. Subject areas of interest were Electronic Countermeasures, Direction Finding, Ducting, Earth/Satellite and Satellite/Earth Paths, Laser/Range Finding, Lobe Control, Over-the-Horizon Propagation, and Troposcatter Techniques. Data on citation indexing which had been collected during Phase IV were rearranged in order to learn of the productivity of the respective authors and of their relation to corporate entities responsible for the literature articles that had been published. In addition, a total of 221 document additions was made to the data base and 21 descriptors were added to the EMPIRE Thesaurus. (Author)
