| Abstract(in English) | We control group velocity of electromagnetic waves in a metamaterial mimicking electromagnetically induced transparency, which is a quantum interference phenomenon and occurs in A-type three-state atoms. The unit cell of the metamaterial is designed to have coupled two resonant modes: a bright mode and a dark mode. The coupling strength between these two modes is determined by the electromagnetic field gradient. The group velocity at the transparency frequency can be varied by varying the incident angle of the electromagnetic plane waves. By tilting a single layer of the metamaterial, the group velocity of a microwave pulse is varied experimentally. |
