whenever a charged particle moves across an inhomogeneous region. One feature
of transition radiation is that it can create light emission at arbitrary
frequency under any particle velocity. Therefore, transition radiation is of
significant importance to both fundamental science and practical applications.
In this paper, we provide a brief historical review of transition radiation and
its recent development. Moreover, we pay special attention to four typical
applications of transition radiation, namely the detection of high-energy
particles, coherent radiation sources, beam diagnosis, and excitation of
surface waves. Finally, we give an outlook for the research tendency of
transition radiation, especially its flexible manipulation by exploiting
artificially-engineered materials and nanostructures, such as gain materials,
metamaterials, spatial-temporal materials, meta-boundaries, and layered
structures with a periodic or non-periodic stacking. | | Source: | arXiv, 2301.00333 | | Services: | Forum | Review | PDF | Favorites | |
