Claim 13:
14. The system of claim 13, further comprising a frequency generation circuit to synthesize required high frequency signals, where the frequency generation circuit include at least one Voltage Controlled Oscillator or at least one Phase-locked loop; the frequency generation circuit further comprises a plurality of directional couplers as the main wave coupling structure; the frequency generation circuit further comprises two gain and phase detectors to extract a reflection coefficient magnitude from an incident and a reflected wave; the frequency generation circuit further comprises phase shifting at one input of the detectors to enable a full 0-360 degrees phase measurement; the frequency generation circuit further comprises an attenuator in the coupled incident wave path to balance its magnitude level with that of the coupled reflected wave.
