4.1 Coupling Cross Section

Abstract—The field-to-cable coupling cross section is proposed to evaluate the coupling performance of a single-braided coaxial cable. In addition, a new definition for the coax shielding effectiveness is suggested. Both the coupling cross section and the shielding effectiveness of a 1.25 m-length RG 58 C/U 50Ω coax are measured by employing both the mode-tuned reverberation chamber and GTEM cell methodologies. The detailed measurement set-ups and results are presented. The mode-tuned reverberation chamber methodology is proven to be beneficial for assessing the cable shielding and couplin
