Abstract-A generalized equivalent cable bundle method (GECBM) is presented for modeling electromagnetic (EM) compatibility issues of complex cable bundle terminated in arbitrary loads. By introducing a new grouping criterion, complex cable bundles terminated in arbitrary loads can be reasonably simplified through a generalized equivalence procedure. The reduced cable bundle model can be used for modeling electromagnetic immunity, emission and crosstalk problems. The complexity and the computation time for the complete cable bundle modeling has been significantly reduced and fairly good precision is maintained. Numerical simulations are given to validate the efficiency and advantages of the method.
In this work, we explore the existence of spoof surface plasmons (SSPs) supported by deep-subwavelength high-contrast gratings (HCGs) on a perfect electric conductor plane. The dispersion relation of the HCGs-based SSPs is derived analyt- ically by combining multimode network theory with rigorous mode matching method, which has nearly the same form with and can be degenerated into that of the SSPs arising from deep-subwavelength metallic gratings (MGs). Numerical simula- tions validate the analytical dispersion relation and an effective medium approximation is also presented to obtain the same analytical dispersion formula. This work sets up a unified theoretical framework for SSPs and opens up new vistas in surface plasmon optics.
Abstract-This paper presents a multiconductor reduction method for modeling electromagnetic crosstalk of complex cable bundles in the vicinity of a 60 degree corner. Based on the image theory and wide separation assumption, the per-unit-length parameters of the cable bundle can be obtained analytically. A modified six-step procedure is established to define the electrical and geometrical characteristics of the reduced cable bundle model compared with the original equivalent cable bundle method (ECBM). Numerical simulations are performed to demonstrate the viability and effectiveness of the method. This work can find wide applications in real environments.
