Abstract

Abstract

This paper propose a quantitative analysis on the electromagnetic leakage from a shielded-twist-pair with a transverse slot. The mechanism of electromagnetic leakage is analyzed, and then the slotted shielded-twist-pair is regarded as a cascaded network. By applying the hybrid-method, which is the combination of the chain-parameter-equation, the finite-element-method and the subcell-FDTD-method, the electromagnetic leakage from the transverse slot on the shield of the twist-pair are simulated. The results show that, below the frequency of 500MHz, the leaked energy from the slotted shielded-twist-pair is no more than 1% even if the shield layer is cut off.
