Abstract :
The use of a phase-switched-screen boundary to actively control the electromagnetic scattering properties of an uncovered planar PEC surface is described. The structure incorporates a single active layer but is capable of tuning a reflectivity null of better than -20 dB over a significant bandwidth. Theoretical predictions are compared to measured data derived from an experimental system
