Показать описание
This is the demonstration of applying Reconfigurable Intelligent Surface (RIS)/Coding metasurface in Wireless communications.
In this demo, we present 3 different beamforming techniques with RIS.
1. Conjugate Beamforming
2. Compressive Sensing Beamforming
3. Switch Beams Beamforming
The OFDM signal sent by the Tx will be reflected by the IRS which steers the EM beam toward the Rx.

Hi Tran. I saw you submitted the paper on October 2019. How long did it take to finish the project.
