It can be observed that the phase difference between two neighboring states falls in the range (9015, 90+15) around the frequency of 3.2 GHz. The calibration measurements are organized into a column vector e. To characterize the inhomogeneous current induced on metasurface particle, the particle is regarded as an array of 33 point-like dipoles, stacked in a 9-length column vector of p. Apparently, the calibration vector e is linearly related to the vector p through e=Gp, where the entries of G come from the three-dimensional Greens function in free space.
