    "abstract": "We study theoretically the effect of ultraslow phase and group velocities in\nan anisotropic metamaterial. The ultraslow phase propagation is induced by the\nhyperbolic dispersion relation. While the inherent physics underlying the slow\ngroup velocity are collective operations of the frequency and spatial\ndispersion. We show that a Gaussian wave packet exhibits simultaneous slow\nphase and group velocities which depend on the choice of incident angles and\nprincipal axis angles. The anisotrocpic metamaterial slab can be constructed\nand the ultraslow phase and group velocities can be measured experimentally.",
