Metamaterials, with effective negative permittivity and/or negative permeability, have paid much attention in recent years. We present the results on slow light and omnidirectional resonances in the metamaterial-based structures. We have found that the group velocity vanishes in the planar and cylindrical waveguides consisting of the left-handed metamaterial core and the single-negative-permittivity...
To study levitation drift further, i.e., the gap between a superconductor and a permanent magnet varying with time in high-Tc superconducting levitation systems, drift velocity is introduced. Based on the numerical simulations of the dynamic response of a levitated body, and according to the essential reasons for drift, the drift velocity is first divided into two regimes: Vff [related to flux flow...
