Inverse Doppler Effect
Year: 2004
Keywords: group velocity, inverse Doppler effect, phase velocity, Sedden and Bearpark
Ordinarily, the wavelength of radiation will be increased upon reflection from a receding surface. An electrical circuit has been constructed in which RF generated by a disturbance reflects off the receding disturbance with a shorter wavelength. Following this sleight of hand requires keeping track of the phase and group velocities.
