Systems and methods relating to independent control of a reflected electromagnetic wave’s phase and magnitude. A reflective unit cell with independently controllable resistance and capacitance allows for control of the magnitude and phase of the reflected wave. In one implementation, the unit cell uses coupled resonators, with each resonator having independently controllable parameters. The coupled resonators may be a dipole ring resonator nested with a split ring resonator. The dipole ring resonator is loaded with a tunable resistive element while the split ring resonator is loaded with a tunable capacitor. By independently adjusting the resistance and the capacitance of the resonators, the magnitude and phase of the reflected wave can be controlled.
