a The measurement configuration of the dynamic beamforming. b–d Measurement configurations of three ISAC scenarios. In Scenario #1, the signal is transmitted non-line-of-sight (NLoS) between the transmitter and the receiver through the metasurface, while the propagation path is blocked by a triangular metallic obstacle. The surrounding absorbing materials are used to eliminate the multipath effect. In Scenario #2, the signal is transmitted between the transmitter and the receiver in an open corridor environment with distinct multipath effects. In Scenario #3, the signal is transmitted line-of-sight (LoS) between the transmitter and the receiver through the metasurface without any obstacle in the propagation path.
