摘要
Abstract The dual-band analog electromagnetically induced transparency (EIT) with intriguing toroidal has been presented at microwave frequency. The proposed construction is composed of the split resonant rings with different sizes in two layers to induce dual-toroidal resonance. By optimizing the structure, two transparency peaks derived from strengthened toroidal could attain to 0.97 at 5.36 GHz and 0.94 at 10.23 GHz, which could be certified by numerical simulation, near-field distribution and scattered power of far-field. The experiment and simulation are almost consistent, and the dual-toroidal analog-EIT could have potential applications in many fields, such as ultrasensitive sensing and secure data communication.
