Abstract :
We report results on “hot” modeling of an O-type oscillator with a metamaterial-like periodic electrodynamic structure. The structure, having its spatial period much less than the wavelength, exhibits extremely low group velocity and, at the location of the propagating electron beam, supports the longitudinal component of electric field of a fair amplitude, thus, providing a sufficient value of the Pierce parameter.
