discoverers are calling it. Physicists in England have demonstrated a form of motion-induced
frequency shift that is opposite of Doppler. This inverse Doppler was first predicted
in the 1940s, and produces a frequency shift 100k times greater than Doppler. A
contraption comprised of a bank of capacitors and inductors is pulsed with up to
100 A of current, which sets up the necessary conditions for Doppler inversion.
What basically is a case of really bad VSWR creates a series of multiplying wavefront
compressions yield frequency factors of 20 or greater during each boundary reflection.
Multiple passes rapidly generate very high shifts. The terahertz frequencies produced
by this method are planned for use in medical imaging, security scanning and many
other applications. |
