The transmission of electromagnetic waves (such as lasers) in plasma is a fundamental issue in plasma physics. In general, electromagnetic waves cannot be transmitted in high-density plasma, but their transmission and energy transfer play a crucial role in applications such as fast ignition laser fusion, laser particle acceleration, and ultra short and ultra bright radiation sources.In 1996, S. fr...
Introduction and application of a micro optical platform using metasurfacesMetasurfaces are artificial materials that excel in manipulating perception. Due to the fact that metasurfaces can reduce the size of lenses to one thousandth of traditional lenses, they have attracted great attention as optical components for miniaturization of next-generation virtual reality, augmented reality, and LiDAR ...
