Electromagnetically Induced Transparent Electromagnetic Properties Based on Multimode Coupling

Abstract Metamaterials are a class of non-natural materials with special properties, the microstructure which does not exist in nature. By artificially designing structure such materials, they can acquire electromagnetic properties that conventional nature do have. Electromagnetically induced transparency refers to process quantum interference effect between atomic energy levels microscopic systems, makes an energy-transmitting window appear original energy-absorbing region, simply put, medium strongly absorbs certain frequency light beam, and when another beam is applied, absorption first by will be greatly reduced or no longer absorbed. This phenomenon called electromagnetically transparency, EIT for short. In this paper, we combine graphene material improve manipulability obtain controllable based on multi-mode coupled extension.
