Abstract
A ferroelectric focussing and defocussing device for operation at millimeter wavelengths applicable for use as a component in radar systems. Electrodes direct fields reversibly and continuously modify the refractive character of the ferroelectric material of the device as incoming radiation seeks to proceed along the optic axis of the material. The device includes first and second material media sharing complementary sides with Fresnel contours.
