“…Therefore, any realistic implementation of such proposals will necessarily experience performance deterioration due to frequency dispersion of the material properties. We note that several recent works [97], [98], [99] have studied material dispersion effects in the context of temporal modulations. We believe further investigations in this area are important to enhance our understanding of time-varying materials and may lead to improved designs with more realistic properties.…”

Time-varying components provide an exceptional opportunity to explore novel means for building 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 physical bounds, such as the Bode-Fano limit, the Chu limit, etc. Here, we overview this emerging research area and provide a concise and systematic summary of the most relevant applications for which the relevant physical bounds can be overcome through time-varying elements. Besides leading to devices with superior performances, such research endeavors open new possibilities and might offer insight towards future all-electromagnetic/optical technologies.
