Development of Broad-Band Electromagnetic Absorbers for Electroexplosive Devices
Abstract
Progress is reported on the design and fabrication of several coaxial attenuators, both insulated and uninsulated. Two other barrel type attenuators were built, and their attenuation capabilities measured. Suitable lossy ferrites were produced in limited numbers. The effect of varying the cooling rate is still not clear but natural cooling outside the furnace in a nitrogen atmosphere shows promise. Use of preformed high dielectric-constant insulators on ferrite at tenuators resulted in a substantial decrease in attenuation from that of uninsulated assemblies. A barrel attenuator using insulated ferrite beads is one possible approach to the problem of attaining the greatest attenuation in the smallest space.
