ABSTRACT:
A scanner (13) of ferroelectric material (17) for redirecting the orientation of a beam (22) of millimeter wavelength radiation. The scanner (13) includes parallel input and output sides with matching layers (44). Adjacent and opposite parallel wire grid electrodes (31') are addressed with progressive voltage difference excitation levels across the face of the ferroelectric material in order progressively to modify the refractive index distribution of the scanner and thereby conduct effective beam steering.
