Outline of Final Research Achievements

We have investigated slow group velocity propagation of electromagnetic waves and enhanced nonlinear phenomena associated with the slow group velocity propagation in metamaterials that mimics electromagnetically induced transparency (EIT) in quantum optics. The group index of 27000 was achieved in an EIT-like metamaterial composed of coupled resonators with indirect coupling. The characteristic of the EIT-like metamaterial was dynamically changed to two kinds of Lorentz type metamaterials using an air discharge plasma caused by a highly enhanced local electric field associated with the slow group velocity propagation. The metamaterial can be applied, for example, to limiters and switches for electromagnetic waves.
