摘要

摘要具有非线性部件的接收和散射结构的电磁特性很难预测，尤其是在涉及多个非线性载荷的情况下。在这篇文章中，分析了具有两个二极管作为非线性负载的框架天线。该接收天线结构由携带瞬态HPEM信号的偏振平面波照射。然后，给定的任务是计算天线附近的电场分布。为此，导出了非线性加载结构的宏模型，该宏模型将瞬态信号与在观测点测量的电场相关联。因此，可以看到如何应用最新的宏建模技术来逐步解决给定的问题。这为通过通用框架进一步分析给定非线性载荷的相互作用提供了可能性。

Calculation of the Combined Electric Field Response of Multiple Nonlinear Antenna Loads due to HPEM Excitation

Abstract. The electromagnetic properties of receiving and scattering structures with nonlinear components are difficult to predict, especially if more than one nonlinear load is involved. In this contribution a frame antenna with two diodes that act as nonlinear loads is analyzed. This receiving antenna structure is illuminated by a polarized plane wave, carrying a transient HPEM signal. It is then the given task to compute the electric field distribution in the vicinity of the antenna. To this end, a macromodel of the nonlinearly loaded structure that relates the transient signal to the electric field measured at an observation point is derived. As a result it is seen how recent macromodeling techniques can be applied to solve the given problem step by step. This provides the possibility to further analyze the interaction of the given nonlinear loads by a general framework.
