Abstract-This paper presents a synthetic concept on eliminating crosstalk within multiconductor transmission lines (MTLs). Firstly, the method of moments (MoM) is used to calculate the per-unitlength (PUL) parameters of transmission lines. Secondly, the crosstalk is predicted using SPICE circuit simulator. Finally, three methods eliminating crosstalk are used synthetically to design the structure of MTLs. According to the results simulated with software, the effect on eliminating crosstalk by the synthetic design is quite satisfactory. Therefore, the concept may be implimented in practical engineering.

“…So, the analytic method wins general concern of researchers. Now, there are two types of analytic methods mainly: the method based on Bethe aperture coupling theory [2,3] and the method based on transmission line theory [4,5]. The second type is discussed further in this paper.…”

Because of the importance of the electromagnetic interference resistance in the modern life, the electromagnetic shielding of the piezoelectric vibration acceleration sensor is analyzed in this paper. The shell of the piezoelectric vibration acceleration sensor is taken as a three-layer rectangular cavity with apertures. The shielding effectiveness of the shell irradiated by plane electromagnetic wave is modelled using transmission line theory. In the modeling process, incident angle and polarization angle of the plane electromagnetic wave are introduced, and the scattering voltage produced on the outer aperture is taken as the radiation source. The aperture is taken as the asymmetrical coplanar stripline and the rectangular cavity is taken as a rectangular waveguide with one end completely open and another end completely closed. The shielding effectiveness of the cavity is calculated using transmission line theory. Compared to the others before, this method improves the completeness of the model, computation speed, and the shielding effectiveness which supplies good reference for engineering practice.

“…EMI test facilities are designed to keep external ambient fields from degrading test results, as well as to prevent test radiation from interfering with systems not involved in the test. The shielded enclosure performs these functions [2,3], but the walls themselves may cause serious reflections. Such reflections may require the use of RF absorbent material, as in anechoic chambers [4].…”
