Researchers create metasurface that enables multichannel terahertz transmission opticalsociety
"6G networks will likely require more base stations to achieve full signal coverage," said research team leader Fuyu Li from the University of Electronic Science and Technology of China.
The first device they made uses the polarization state of a terahertz wave as a switch to select the information carried by the superpositioned states of vortex and spherical waves. Spherical waves propagate outward in all possible directions while vortex waves have a special helical shape.
After demonstrating both superposition states and multi-channel transmission of vortex and spherical waves theoretically, they also performed simulations and experiments. In the experimental tests, the researchers measured superposition states between the vortex and spherical waves close to the, showing that the device worked well. They also showed that the direction of rotation and intensity of spiral interference stripes produced were consistent with the theoretical and simulated designs.
