From: Chaotic information metasurface for direct physical-layer secure communication
With the chaotic information metasurface, the legitimate transmitter Alice transmits unencrypted information to the legitimate receiver Bob, and the eavesdroppers Eve1, Eve2, Eve3… receive chaotically encrypted information.
