AI Article Synopsis
- Stacking two T-shaped resonators creates electric and magnetic hybridized plasmonic modes, and their head-to-toe arrangement can reverse the hybridization process.
- The frequency difference between resonances can be precisely adjusted by changing the gap between the resonators.
- A negative refractive index near -1 is achieved at 4.3 GHz for TE waves, showing similar left-handed behavior for both parallel and normal wave vectors, making this design suitable for terahertz and infrared metamaterials.
Article Abstract
Electric and magnetic hybridized plasmonic modes are obtained by stacking two T-shaped resonators. We show that head-to-toe configuration leads to inverse the hybridization. The frequency shift between the resonances is finely controlled by adjusting the gap between the two resonators. A negative refractive index close to -1 is numerically and experimentally demonstrated at 4.3 GHz for TE waves. This left-handed behavior is similar for parallel and normal TE incident wave vectors. The proposed double-T unit cell is well adapted for developing terahertz and IR metamaterials.
