描述了一种简单且计算高效的方法来表示手工制作的随机线束的几何形状，该方法可以在多导体传输线模型中利用，用于预测外部电磁场在线束终端单元中感应的电流。作为说明性示例，考虑在金属地面上方运行并由均匀平面波照射的随机束。通过处理重复模拟（蒙特卡罗方法）产生的数据，观察到感应电流统计的一些重要特性。特别是，结果表明，在所谓的“良好随机化”束中，感应电流大小的概率密度函数在低频下趋于正态，在高频下趋于瑞利。
A simple and computationally efficient method to represent the geometry of hand-made random wire bundles is described, which can be exploited within a multiconductor-transmission-line model for prediction of the currents induced in bundle terminal units by an external electromagnetic field. As an illustrative example, a random bundle running above a metallic ground and illuminated by a uniform plane wave is considered. By processing the data resulting from repeated simulations (Monte Carlo approach), some significant properties of the statistics of the induced currents are observed. Particularly, it is shown that in the so-called “well randomized” bundles the probability density function of the magnitude of the induced currents tends to be Normal at low frequency and Rayleigh at high frequency.
