文摘
- •
An analog of electromagnetically induced transparency in terahertz tubes is proposed.
- •
A single second transverse mode of Bessel distributions is observed in the pass band.
- •
The operating frequency can be linearly controlled by the sputtered gold thickness.
- •
We can effectively manipulate the slow down factor of light by the gold thickness.
- •
The transparency characteristics rely on the transition of multi-mode interactions.
