Paper Abstract

This paper describes a series of experiments and calibration techniques aimed at a better understanding of observed anomalous pulsed microwave composite propagation phenomena. It is demonstrated that early wavefront contributions, associated with the precursor of pulsed microwaves propagating in air-waveguide structures, and observed slightly above the noise level of the system, exhibit small propagation times corresponding to the phase velocity of the pulsed microwave in the dispersive medium. On the other hand, lack of detection sensitivity, can lead to the observation of unphysical large time delays, and be interpreted based on the intuition of the observer, or in the worst of the cases, as noise.
