摘要：
本文通过利用复激励下的特殊散射响应，提供了纯无功负载阻抗匹配的实验证据。研究首先对任意无功负载的反射特性进行了理论分析，并确定了能够在信号施加期间将纯无功负载转变为虚拟电阻负载的适当激励。为了最小化负载与传输线之间的反射，激励必须具有复频率，从而产生具有定制时间包络的传播信号。本工作的目标是设计并在微波电路中首次实验证明这种反常散射行为，表明时间调制信号可以作为一种新的自由度来实现阻抗匹配，而无需引入匹配网络或电阻元件——这些元件通常用于确保功率耗散从而实现零反射。所提出的匹配策略不会改变仍然无损耗的无功负载，从而实现了反常的终端条件：能量既不耗散也不反射，而是无限地积累在无功负载中。一旦施加的信号发生变化或停止，存储的能量就会从负载中泄漏出来。
英文摘要：
The experimental evidence of purely reactive loads impedance matching is here provided by exploiting the special scattering response under complex excitations. The study starts with a theoretical analysis of the reflection properties of an arbitrary reactive load and identifies the proper excitation able to transform the purely reactive load into a virtual resistive load during the time the signal is applied. To minimize reflections between the load and the transmission line, the excitation must have a complex frequency, leading to a propagating signal with a tailored temporal envelope. The aim of this work is to design and, for the first time,experimentally demonstrate this anomalous scattering behavior in microwave circuits, showing that the time-modulated signals can be exploited as a new degree of freedom for achieving impedance matching without introducing neither a matching network nor resistive elements, that are typically used for ensuring power dissipation and, thus, zero reflection. The proposed matching strategy does not alter the reactive load that is still lossless, enabling an anomalous termination condition where the energy is not dissipated nor reflected, but indefinitely accumulated in the reactive load. The stored energy leaks out the load as soon as the applied signal changes or stops.
