Simulating laser pulses by practical test functions and progressive waves

Abstract

This study presents simulations performed in Matlab for the change of dielectric properties of mixtures of fatty acids under the influence of external optical or electrical pulses. These simulations are based on the use of practical test-functions. It is shown that, for an external observer, the behavior of the material medium for an alternating input of high-frequency (corresponding to an optical pulse) presents a single oscillation on the whole working interval, similar to the dynamics of ε noticed during the experiments. For the case of suddenly-applied electric fields, it is shown that the use of a similar dynamical model, in conjunction with the hypothesis of progressive waves generated inside mixtures of fatty acids by suddenly-applied electric fields, can simulate the dynamics of electrical properties of such mixtures in a correct manner. © Springer-Verlag Berlin Heidelberg 2005.
