A reflection controller for modifying electromagnetic reflections from a surface includes a conducting patch being positioned proximate to an electromagnetically reflecting surface. The floating conducting patch includes an electrical conductor at a floating potential positioned on a dielectric substrate where at least one of a dielectric thickness, dielectric constant, or the dimensions of the electrical conductor are chosen to reduces retro-reflection of incident radiation.

An apparatus for determining V&#x3c0; of an optical modulator includes an RF source that generates a variable power RF modulation signal for modulating an optical modulator. An optical detector detects a modulated optical signal generated by the optical modulator and generates an electrical detection signal in response to the detected modulated optical signal. An RF power meter measures an RF detection signal power to determine a minimum RF detection signal power, an RF modulation signal power corresponding to the minimum RF detection signal power being used to calculate V&#x3c0; of the optical modulator.
