Observation of the Inherent Chiral Smith-Purcell Effect via Symmetry Breaking
Juan-Feng Zhu, Fei Chen, Jun-Xuan Chen +9
The Smith-Purcell effect arises when charged particles move near a periodic structure, emitting radiation. Conventional approaches for generating chiral Smith-Purcell radiation rel…
