作者讨论了电磁感应透明（EIT）超材料的设计和建模及其在传感和具有非线性响应的介质中的应用。描述经典EIT系统的最简单模型是一组两个耦合质量弹簧振荡器或两个由并联电容器耦合的RLC电路。作者认为，电磁感应吸收（EIA）的经典模拟可能对光谱学和传感应用感兴趣，因为它产生具有窄带宽的光谱特征。EIT超材料的光谱特征可以非常窄-仅受耗散损耗限制，而不受辐射损耗限制-并且暗谐振器中的大场使其对（介电）环境的变化非常敏感。EIT超材料的第二个应用是构造具有非线性响应的超材料。
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.
