Physical Review Accelerators and Beams
Preserved Fulltext
This paper considers how the finite dimensions of a photonic crystal placed inside a resonator or waveguide affect the law of electron beam instability. The dispersion equations describing e-beam instability in the finite photonic crystal placed inside the resonator or waveguide (a bounded photonic crystal) are obtained. Application of photonic crystals for development of THz sources at electron beam current densities available at modern accelerators is discussed.
