Abstract :
Modified metallic metamaterials are known to provide external radiation from Cerenkov-like modes which can be excited using an electron bunch. Extremely strong electromagnetic field enhancement could be formed for compact, efficient free-electron lasers with open metallic structures. The numerical and experimental works will be presented in detail.
