Frequency Selective Side Absorber for a Meander Line.
DEPARTMENT OF THE ARMY WASHINGTON DC
Pagination or Media Count:
A meander line slow wave structure mounted on ceramic bars for a microwave device such as an injected beam crossed-field amplifier includes frequency selective atttenuator means which will preferentially attenuate waves at frequencies near and within the stopband of the slow wave structure by the placement of side absorber bars of attenuating material adjacent to the outer side surfaces of a plurality of meander line finger segments. The frequency selective absorber material, in its preferred form, comprises a beryllia and silicon carbide ceramic composition which is additionally adapted to accommodate metallic absorber top plates, nichrome films, and slotted side ring configurations.
