Nanophotonics for tailoring radiation from fast electrons

Nanophotonic methods provide intriguing options for manipulating scintillation phenomena. We will outline recent developments in this domain, along with our theoretical framework for modeling these occurrences, supported by our experimental findings. Additionally, Smith-Purcell radiation, characterized by fast electrons interacting with nano-structured materials to produce light, offers a broad spectrum of possibilities for creation of novel light sources. We will discuss our new theoretical framework designed to comprehend and tailor such phenomena, as well as our techniques for boosting Smith-Purcell radiation.
