“…The bright mode coupling part of the energy to the dark mode, so that the Mie resonance of the dark mode is enhanced. [31] At the two transmission zeros, the energy coupling to the resonators is primarily due to electric field coupling, while at the transmission peaks, the energy coupling to the resonators is primarily due to magnetic field coupling. Furthermore, it can be seen that the dielectric columns have higher energy in the vicinity of the centerline, because they not only couple with the CW, but also exhibit resonances between each other.…”

An electromagnetically induced transparency metamaterial (EITM) based on dielectric resonators is presented in this paper, which consists of a cut wire (CW) and ten dielectric columns. Destructive interference between the CW, which is a branch of the microstrip line, and the dielectric resonators causes the EIT phenomenon. The simulation results show that the dielectric‐based EITM designed can obtain a transmission peak of 0.938 at 2.17 GHz, and the two‐oscillator model is utilized to verify the effectiveness of the structure. In addition, samples of the dielectric‐based EITM are also fabricated and the effectiveness of the metamaterial is experimentally verified. The proposed metamaterial has several advantages, including high efficiency, low loss, a simple structure, and ease of manufacture, which has good prospects for application in the fields of electromagnetic switches, sensors, and nonlinear metamaterials.
