abstract = "The fault diagnosis of reconfigurable intelligent surfaces (RISs) is essential to their optimal performance. In this paper, a fault model and its diagnosis method of RISs are presented to identify the fault of phase control deviation. Instead of inverting the phase of a single element each time in the conventional method, this paper employs a Hadamard matrix inversion strategy robust to measurement noise. Under the same measurement noise, the presented strategy achieves a phase diagnosis error of ±7°, while an error of ±83° is obtained by the conventional phase-inverting strategy.",
