How Smith-Purcell Radiation Occurs? Since its discovery in 1953, Smith-Purcell Radiation (SPR) has been a topic of interest for scientists and researchers [1]. SPR occurs when an electron beam passes over a periodic metallic grating, and it has been observed in a wide range of frequencies, from visible light to Tera Hertz (THz) waves. With…
