论文摘要
时变的系统开放了有趣的机会，可以探索有效电磁设备设计的新颖方法。尽管这种探索可以追溯到半个多世纪以前，但近年来，人们对动态电磁系统的设计产生了重新兴趣并增加了兴趣。这种复兴是由于超越常规设备的性能的愿望而部分推动了这种兴起，并启用可以挑战各种良好的性能界限的系统，例如Bode-Fano限制，CHU限制等。在这里，我们概述了这个新兴的研究领域，并提供了最相关的应用程序，可以通过随时间变化的元素来克服相关性能界限。除了启用具有出色性能指标的设备外，此类努力还可能打开全新的机会，并为未来的电磁和光学技术提供见解。
Time-varying systems open intriguing opportunities to explore novel approaches in the design of efficient electromagnetic devices. While such explorations date back to more than half a century ago, recent years have experienced a renewed and increased interest into the design of dynamic electromagnetic systems. This resurgence has been partly fueled by the desire to surpass the performance of conventional devices, and to enable systems that can challenge various well-established performance bounds, such as the Bode-Fano limit, the Chu limit, and others. Here, we overview this emerging research area and provide a concise and systematic summary of the most relevant applications for which the relevant performance bounds can be overcome through time-varying elements. In addition to enabling devices with superior performance metrics, such research endeavors may open entirely new opportunities and offer insight towards future electromagnetic and optical technologies.
