Abstract:

Investigations were made to extend the determination of the interference characteristics of U. S. Army communication equipment to include the near-field emission and susceptibility characteristics. The objectives of these investigations are 1 the determination of the most economical and practical means for establishing a controlled electromagnetic environment for measuring nearfield radiated and susceptibility interference characteristics of electronic equipments and 2 development of measurement techniques for measuring near-field radiated and susceptibility interference characteristics of electronic equipments in the above controlled electromagnetic environment which can be correlated with open-field measurements. An investigation to evaluate a measurement technique, in which the test antenna is shielded in all but the desired direction by means of a metal hood lined with absorbing material, is described. The development of a broadband balun and antenna for use in this technique is included. The fabrication of model shielded enclosures and their use in evaluating enclosure shaping factors, absorbing materials, and absorbing material placements within shielded enclosures are described.
