请大家帮忙翻译下面一段话电磁波传播方面的，这是一篇论文里的一段，对小虫很重要，翻译得越详细越好！小虫在这里谢谢大家！ In order to define the points away from the physical boundaries of a discontinuity where the fields of HOMs vanish, hence the electrical boundaries of the discontinuity, the following methodology was used: First of all, the cut-off frequency of Lo-HOM that is excited on the interconnecting traces was computed, to make sure that the HOMs are not propagating. This was then followed by a computation of the attenuation constant, α, of this Lo HOM. Using α, the range of existence of fields of the excited HOMs (from the point of excitation away, towards the end of the trace) was deduced. Since the end of the discontinuity effect marks an end of the disturbance of the fundamental mode by the HOMs, the effect of the excited HOMs on the fundamental mode was studied with the aid of a 3D full-wave solver, taking into consideration the range of existence of the fields of HOMs computed from α. From the field computation results, the variation of power propagated by the fundamental mode was critically studied using the Poynting theorem. It was deduced, that in the immediate vicinity of the discontinuity where the fields of the evanescent modes are still too large, the imaginary part of the Poynting theorem is also very large. But, it decays exponentially with distance away from the discontinuity since these fields also decay exponentially. The end of the discontinuity effect is marked by a small and approximately constant value of this imaginary part and the field distribution on the trace then resembles that of a uniform transmission line. This variation in power was also seen in the extracted S-parameters, since these S-parameters were derived from power. As the end of the discontinuity effect approached, the magnitude of the reflection coefficient of the S-parameter, computed at a single frequency point when only the fundamental mode is excited, remain approximately constant.
