Abstract : A single element line scanner applicable to millimeter or submillimeter wave beam steering which includes a semiconductor waveguide made of a high resistivity bulk single crystal intrinsic semiconductor material such as silicon is described. Parallel spaced radiator elements are disposed on one major or top surface of the semiconductor waveguide transverse to the direction of wave propagation along the waveguide. Parallel spaced PIN diodes are disposed on the other or bottom major surface of the semiconductor waveguide transverse to the direction of wave propagation. The PIN diodes are spaced close enough to prevent radiation from escaping outwardly from the bottom major surface and are provided with a variable forward bias to produce a conductivity sheet.
