- •
We present a broadband linear polarization converter of transmission mode in the terahertz region.
- •
The converter can convert linearly polarized wave into its cross polarization with conversion rate (PCR) more than 95％ .
- •
The in-depth analysis of physical mechanism is illustrated by surface current and electrical field distributions.
