An analytical approach for calculating load response of a transmission line with interference source in interconnected equipment

In this paper, an efficient analytical approach for calculating the load response of a transmission line(TL) with interference source in interconnected equipment was proposed based on Bethe's theory and BLT equation. Using the corresponding dyadic Green's function and Bethe's theory, the fields around the TL excited by a hertzian dipole is determined. Then, the load disturbance is obtained with the help of Agrawal's model and BLT equation. The results are in good agreement with CST simulation, which establishes the validity of the analytical method. Compared to numerical simulation, the proposed method possesses better efficiency and consumes less memory.
