Lenses based on plasma could offer an alternative to electronic beam steering at high frequencies (∼100 GHz) and high powers. Presented are beam deflection measurements for a lens which exhibits wide angle deflections (25°), good collimation and rapid beam steering (∼100 µs). A practical prototpe is described.
