| Outline of Final Research Achievements |
We investigate a method to store propagating electromagnetic waves in an artificial medium called metamaterial and retrieve the stored waves at arbitrary timing. The final goal of this research is to realize storage and retrieval of electromagnetic waves with metamaterials implementing electromagnetically induced transparency, which has been extensively investigated in atomic systems. We experimentally demonstrate the storage and retrieval of microwaves using a metamaterial loaded with nonlinear capacitances. In addition, we propose a nonlinear dielectric metamaterial that implements electromagnetically induced transparency in optical regions and demonstrate the performance in computer simulations.
