[Kapitel]

The authors discuss the design and modeling of electromagnetically induced transparency (EIT) metamaterials and some work on its applications for sensing and for media with nonlinear response. The simplest model to describe classical EIT systems is a set of two coupled mass-spring oscillators or two RLC circuits coupled by a shunt capacitor. The authors believe the classical analog of electromagnetically induced absorption (EIA) may be interesting for applications in spectroscopy and sensing, since it produces a spectral feature with a narrow bandwidth. spectral feature of EIT metamaterials can be very narrow - only limited by dissipative loss, not by radiation loss - and the large fields in the dark resonator make it very sensitive to changes in the (dielectric) environment. A second application of EIT metamaterials is the construction of metamaterials with nonlinear response.
