Abstract:
This paper re-examines the dynamic Casimir effect as a possible mechanism for propulsion. Previous investigations assumed mechanical motion of a mirror to generate thrust. In this case, because of the finite strength of materials and the high frequencies necessary, the amplitudes of motion must be restricted to the nanometer range. To permit larger amplitudes, an epitaxial stack of transparent semiconductor laminae is proposed. Voltage is rapidly switched to successive lamina, creating continuous, large amplitude motion of a reflective surface without mechanical contrivances. The paper provides relativistic results for large amplitude motion. With centimeter-level magnitudes, propulsive forces are raised to significant levels.
