Electromagnetic Leakage From Shielded Cables By Pigtail Effect

Abstract

In this paper, theoretical analyses and exper. imental results are carried out on the electromagnetic leak. age from shielded cables caused by pigtail effect. Calcula. tions of the leakage are presented on the basis of transmis. sion line theory and antenna theory, and are in excellent agreement with the experiment. Finally, certain protective methods and techniques are introduced, which exhibit at least 30 dB suppressions against the pigtail effect.
