Slow Wave Applications of Electromagnetically Induced Transparency in Microstrip Resonator

Abstract We report a novel guided-wave resonator that supports multiple bands of electromagnetically induced transparency (EIT). The platform for the spatial and spectral interference is obtained by a microstrip transmission line loaded with proximity-coupled open-circuited stubs. We show experiment...
