This paper presents an analysis of the radiated susceptibility of multiconductor shielded cables within complex structures following a hybrid method using moments (MoM) circuit models. The MoM code was used to compute the currents on the shielding induced by an external electromagnetic field and incorporated into a circuit model. The proposed method can be employed for nonlinear loads. The method was tested on two cases: coaxial shielded cables inside a cavity and a car with complex wiring, including a coaxial cable, a twinax cable (a cable with two parallel wires), and a triaxial cable (a cable with three parallel wires), all of which are excited by an incident plane wave. The proposed method provides high accuracy and significant speed gain, and its results are in good agreement with those obtained in other studies.

This article introduces a filter cable design featuring an insulated cylinder that has been coated using a defected conductor transmission structure (DCTS). This unique feature enables the cable to possess distributed filter advantages throughout its length. The DCTS, featuring a well-designed etched pattern, serves as a boundary condition for transmitting specific frequency electromagnetic waves and effectively performs the same filtering function as a lumped filter circuit. To validate this concept, a lowpass filter cable is proposed, which incorporates six-slot-ring defected structures. The cable utilizes polytetrafluoroethylene (PTFE) as the inner dielectric, encased within a flexible printed circuit board (FPCB)-manufactured DCTS. With precise dimensions of a 2.4 mm diameter and a 340 mm length, the proposed filter cable demonstrates performance, indicated by a minimal insertion loss of under 0.38 dB below 6 GHz in the passband, and a rejection surpassing 43 dB at 7.7-25 GHz in the stopband. By comparison, traditional coaxial cables lack these filtering capabilities, making the filter cable with DCTS a viable choice for addressing electromagnetic compatibility (EMC) concerns.

Electrical cables, often referred to as ‘blood vessels’ and ‘nerves’ of the industry, play a vital role in the connection of electrical devices. However, traditional cables that lack distributed filtering functions are usually the primary coupling path for electromagnetic compatibility (EMC) problems. An innovative design for a filtering cable, which incorporates insulated electrical wires coated with a specific defected conductor layer (DCL), enables it to achieve distributed filtering advantages along its axis. Microwave network analysis is employed to build the two-port network model of filtering cable, which efficiently analyzes the cascading characteristics of periodic or aperiodic filtering cables. To validate, the flexible printed circuit board (FPCB) with sawtooth dumbbell-shaped DCL and mounted by capacitors is wrapped around the stripped section of the coaxial cable to manufacture a multi-stopband filtering cable. Simulated and measured results demonstrate that the proposed filtering cable can be effectively suppressed in the stopband, which can be adjusted by changing the values of capacitors.
