本文提出了一种新的模式搅拌室随机电磁环境的数值模拟方法。该方法基于场的平面波积分表示，采用蒙特卡罗模拟，用数值求和代替解析积分。因此，场生成器被实现为程序。将数值产生的场分布和空间相关函数与用于验证场发生器的解析解进行比较。利用这种发生器，可以对简单传输线结构的场耦合进行数值模拟。将耦合的电流或电压也视为一个随机值，从而计算出线路上的平均值和标准差等参数。对于匹配线的特殊情况，为了验证数值结果，给出了解析解。该模拟还允许调查沿传输线的耦合电流的统计分布和相关性。大量的模拟结果与测量结果进行了比较。
A new method for the numerical simulation of the stochastic electromagnetic environment of a mode-stirred chamber is presented in this paper. This method is based on the plane-wave integral representation for the fields and uses a Monte Carlo simulation to replace the analytical integration by numerical summation. Therefore, a field generator is implemented as a program. The numerically generated field distributions and spatial correlation functions are compared to the analytical solutions for the validation of the field generator. With this generator, the field coupling to a simple transmission-line structure can be numerically simulated. The coupled current or voltage has to be regarded as a stochastic value as well, and therefore, parameters like the mean value and the standard deviation along the line are calculated. For the special case of a matched line, an analytic solution is introduced in order to validate the numerical results. The simulation also allows for investigating the statistical distribution and correlation of the coupled current along the transmission line. Numerous simulated results are compared with measurements.
