14 September 1994 Observed precursor of pulsed radio waves
Author Affiliations +
Experimental and theoretical analysis on pulsed radio wave propagation measurements, obtained through a series of time domain experiments in open space as well as in a waveguide, indicate that the precursor or the very early wavefront onset, slightly above the noise level, propagates with a speed equal to the phase velocity. Since it is observable, it may be useful for radio messages. Basic principles and experimental support are presented.
