In twisted wire crosstalk research, common-mode traditional alternative inverted model ignores cross section distance. A new differential-mode twist wire pair crosstalk model considering cross distance is established and the frequency domain of the model is analyzed in this paper with the method of establishing circuit model, mathematical model and solving the parameter matrix chain. The results show...
Calculating the effective parameters (permittivity and permeability) in two-phase composite material is very important. In this paper, hierarchical computing method is used to study the equivalent permittivity and permeability of multilayer composite electromagnetic materials, and to obtain the electromagnetic shielding performance of the materials. Firstly, using of Helmholtz theorem gets electric...
The derivatives in the transmission-line equation can be approximated by difference formula which must satisfy CFL condition. LOD-FDTD provides an unconditional stability method to get the updating equation by alternately solving for the implicit and explicit equation, which improves the computational efficiency greatly, and saves computer resources and memory. In this paper, simulation results demonstrate...
