非线性波混沌:二次谐波场的统计

Nonlinear Wave Chaos: Statistics of Second Harmonic Fields

Min Zhou, Edward Ott, Thomas M. Antonsen, Steven M. Anlage

摘要:

波混沌领域的概念已被证明可以成功地预测电大封闭空间中线性电磁场的统计特性。随机耦合模型(RCM)通过结合随机矩阵理论描述的通用特征和特定系统实现的系统特定特征来描述这些特性。在努力将这种方法扩展到非线性域,我们添加一个积极的非线性倍频电路,否则线性波混沌系统,我们测量的统计特性产生的二次谐波字段。我们开发了一个基于RCM的模型,该系统作为两个线性混沌腔耦合的非线性传递函数的装置。谐波场强是两个统计量和非线性特性的乘积。基于测量的计算,基于RCM的模拟,和直接的实验测量的统计结果进行了比较,并显示出良好的协议,在几十年的权力。

英文摘要:

Concepts from the field of wave chaos have been shown to successfully predict the statistical properties of linear electromagnetic fields in electrically large enclosures. The Random Coupling Model (RCM) describes these properties by incorporating both universal features described by Random Matrix Theory and the system-specific features of particular system realizations. In an effort to extend this approach to the nonlinear domain, we add an active nonlinear frequency-doubling circuit to an otherwise linear wave chaotic system, and we measure the statistical properties of the resulting second harmonic fields. We develop an RCM-based model of this system as two linear chaotic cavities coupled by means of a nonlinear transfer function. The harmonic field strengths are predicted to be the product of two statistical quantities and the nonlinearity characteristics. Statistical results from measurement-based calculation, RCM-based simulation, and direct experimental measurements are compared and show good agreement over many decades of power.
