Extended Data Fig. 2

a, A set of voltage combinations selected for the phase-only modulation or the constant-amplitude and 0–360º phase shift. b, Trajectory of the reflection coefficients for the phase-only modulation: it makes a circular ring around the origin, showing the 0–360º phase shift. c, Real part of the electrical field along the x-axis, showing the gradual phase shift that eventually builds up to 360º. d, A set of voltage combinations selected for the amplitude-only modulation. e, Corresponding phasor trajectory that clearly exhibits the constant phase while varying the amplitude from 0 to its full value. f, Real part of the electrical field along the x-axis, showing no change in the phase while the intensity gradually increases.
