Özet:
This dissertation contains three major parts. In the first part, a generalized multi-conductor transmission line (GMTL) method is proposed to model a cable harness. In the GMTL method, all wires of the cable harness take the infinity as the reference. In such a way, the GMTL method takes into account not only the transmission-line mode but also the antenna-mode current on the cable harness. Further, by employing the GMTL method and the mixed-potential integral equations (MPIE) method in a multiple scattering (MS) procedure, it enables an efficient and accurate approach to evaluate the current distribution on a cable harness with a nearby metal surface. Notice that the cable harness is not grounded to the metal surface in this part. In the second part, a hybrid algorithm called the generalized multiple scattering (GMS) method is proposed to efficiently and accurately calculate the current distribution on a cable harness which has several ground connections to a nearby metal surface. This is a simplified case to mimic a cable harness routed inside a vehicle shell. The GMS method uses the GMTL method for the cable harness part and the MPIE method for the rest of the structure including the metal surface and the grounding wires. Neither the GMTL nor the MPIE method alone takes into account the mutual interactions between the cable harness and the rest of the structure. Therefore, an iterative scheme is arranged in the GMS method to compensate the abovementioned interactions. These interactions occur via not only field couplings, but also current conducting through the grounding points on the cable harness. In the third part, the GMTL method is reformulated to cover both straight and bent cable harnesses. The extraction of the per-unit-length inductance and capacitance is also simplified compared to the extraction method described in the first part. Besides, the steepest descent method is utilized to compute the radiation of a cable harness based on the obtained current through the GMTL method. The capability and limitations of the GMTL method are also carefully examined.
