| Zusammenfassung: | A scanner (13) of ferroelectric material (17) for redirecting 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 opposite sense voltage pulses in order to redirect the domain orientation of crystals in selected regions of said ferroelectric material (17). |
