Abstract :
We report results on modeling dispersion diagrams for a novel metamaterial-like design to be used as a slow-wave structure for Cherenkov microwave sources. The structure, having its spatial period much less than the wavelength, exhibits extremely low group velocity and, thus, a promise of large values of the Pierce parameter.
