Superradiant Smith-Purcell radiation (S-SPR) is a kind of free electron radiation with a train of free electron bunches ...

Free electron lasers have unique advantages of high power, wide frequency tunablility and et al, however, they face challenge ...

The basis of SPR analysis is the measurement of changes in the resonance angle as molecules bind to or dissociate from the metal surface. This change can be detected and quantified, providing detailed ...
