چکیده
|
In this paper, an electromagnetically induced transparency-like metamaterial for terahertz is designed. the structure is based on cross-shaped and srrs composite elements. it can achieve dual-frequency transparent window in a wide frequency band and is insensitive to electromagnetic wave polarization. the resonance points of transmission peaks are 198.55 and 254.18 ghz, respectively. the electromagnetic transmittance can reach 95.6% and 97.7%, respectively, which has excellent electromagnetic transmission effect. the measured results are in good agreement with the trend of simulation curve. at the same time, flexible polyimide with stable performance is selected as the base material of metamaterial dielectric, which can be widely used in microwave fields such as filters, sensors, and slow light devices.
