transmission - Script command Lumerical定义功率沿坐标正向为正,反向为负,这是因为监视器法向永远沿坐标正向,而能流密度如果沿负向,那么两者的点积就是负的,所以结果功率为"负".实际上功率不可能是负的,所以使用时前面需要加负号. 不建议使用绝对值,因为有的时候仿真设置不合理,结果...
We Transmission line circuit model,telegraph equations(a hyperbolic partial differential equations),is the starting point of analyzing transmission lines transient process.A simple and quick and effective numerical solution in time domain has been deduced by the aid of circuit theory and computational mat...
In this paper, we introduce a modified FDTD model in order to investigate the behavior of the induced voltage of a non-uniform transmission line (TL) excited by lumped voltage sources or external electromagnetic wave. The parameters to be taken into account for this specific coupling phenomenon ...
Using FDTD method in order to analyze and also visualize acoustic wave propagation in sonic crystals, we have shown wavelength dependency of the transmission property of several sonic crystals and also some examples of acoustic wave guide which are composed of sonic crystals of no full-band-gap. ...
Firstly, the wave transmission through GSs can be investigated through the maximum value of the waveform obtained from the observation point. Figure6shows the normalized transmitted energy versus different thickness obtained by FDTD-HO-PML and CNDG-HO-PML CFLN = 20. It can be observed that...
