Shielding effectiveness of corrugations in corrugated horns

Shielding effectiveness of corrugations in corrugated horns

A moment-method solution is used to obtain new design data for corrugated horns. The current density on the walls of corrugated dihedral horns is evaluated as a function of such corrugation parameters as the tooth density, and the ratio of the gap to the period (of the corrugations). The shielding e...

Zusammenfassung:A moment-method solution is used to obtain new design data for corrugated horns. The current density on the walls of corrugated dihedral horns is evaluated as a function of such corrugation parameters as the tooth density, and the ratio of the gap to the period (of the corrugations). The shielding effectiveness or the capability of the corrugations to prevent the edge of the horn from being illuminated is discussed, as is the question of the efficiency of corrugated horns.
