论文摘要
时变的网络，包括集体元素（例如电阻器，电容器和电感器）积极调节的集体元素组成，已引入了许多新型波浪现象，并见证了近年来的显着发展。本文研究了从变化的电容器变化的散射，以及当适当调节电容时，如何完全反射这种负载。我们从分析得出电容的所需时间依赖性，并显示与其他技术相反，它避免了极端和负值，因此，当电容器被付给DC电压源时，可以以可行的方式实现。我们还从第一原理中得出了这种时间变化的电容器的能量平衡，证明了传入脉冲的能量被转移到调制源中。我们的发现阐明了随着时间变化的电容器的散射，并为宽带脉冲匹配的新方法打开了。
Time-varying networks, consisting of lumped elements, such as resistors, capacitors, and inductors, actively modulated in time, have introduced a host of novel wave phenomena and witnessed a remarkable development during recent years. This paper investigates the scattering from a time varying capacitor and how such a load can be fully reflectionless when the capacitance is suitably modulated in time. We analytically derive the required temporal dependence of the capacitance and show how in contrast to other techniques it avoids extreme and negative values and, as a result, can be implemented in a feasible way, when the capacitor is charged with a DC voltage source. We also derive from first principles the energy balance of such a time-varying capacitor, proving that the energy of an incoming pulse is transferred to the modulation source. Our findings clarify scattering of waves from time-varying capacitors and open up a new way to matching of broadband pulses.
