Vacuum Electronics
How groove height and width reshape the cold-tube dispersion, move the operating frequency, and ultimately control the threshold for coherent THz Smith–Purcell radiation.
Plasma Physics
A detailed single-layer versus two-layer Smith–Purcell radiation guide showing how grating geometry changes dispersion, spatial growth rate, starting current, and the beam-energy range where a second layer is actually useful.
Electronic Materials
Layered materials conduct very differently in-plane and out-of-plane, reshaping current injection beneath vertical contacts.
