DEVELOPMENT OF BROAD-BAND ELECTROMAGNETIC ABSORBERS FOR ELECTRO-EXPLOSIVE DEVICES
Abstract
Identifiers: Toroids, Aquadag, Electroexplosive devices. A discussion of the effects of silvering toroids and the significant increase of attenuation resulting therefrom is given in table form. To eliminate effects of the silver, toroids were painted with an Aquadag solution on the inner and outer diameters. Attenuation values showed an increase but not to the same extent. This is probably because the Aquadag is not as conductive as the silver solution. It remains to be determined if all of the parameters are affected by silvering and to what extent. The ferrous ion content is important in the fabrication of ferrites. A rapid cooling operation has been employed in the procedure and ferrites having over 35 db/cm at 500 mc have been produced. The densities of our ferrites have been increased by using high firing temperatures. Experiments were conducted to determine the effect of a ferrite RF attenuator on different types of firing stimuli.
