Measured and predicted behavior of pulses in Debye- and Lorentz-type materials

Published laboratory measurements are found to agree with two groups´ completely independent asymptotics for the decay and spread of transient pulses in a Debye model, and the spread in a Lorentz model. The measured dc-content pulses decay with depth nearly as x^-12/ (water) and x^-13/ (concrete) in coaxial cables. The measured full-widths at half-maximum spread nearly as the reciprocal of the decay rates.
