We demonstrate computationally the emergence of Brillouin precursors in the material (water) and the fact that the peak of this transient is attenuated at a much slower rate than is the carrier frequency. In the 0.1– 1 THz regime the carrier frequency does not propagate in our calculations. Only the precursors enter the material, and this is in line with experiments reported by Pleshko and Palocz (Phys. Rev. Lett. 22 (1969) 1201). We also implement models that include nonlinearly forced Debye and nonlinear Debye polarization dynamics and demonstrate the importance of nonlinear effects, especially when the amplitude of the input signal is large. This is an important step in understanding high-frequency pulse propagation, and it has potential applications in the assessment of safety standards and in extending current imaging capabilities in both civilian and military uses.}, number={4}, journal={NONLINEAR ANALYSIS-REAL WORLD APPLICATIONS}, author={Banks, HT and Pinter, GA}, year={2004}, month={Sep}, pages={597–612} } @article{banks_medhin_pinter_2004, title={Nonlinear reptation in molecular based hysteresis models for polymers}, volume={62}, ISSN={["1552-4485"]}, DOI={10.1090/qam/2104273}, abstractNote={We extend the linear “stick-slip” models of Doi-Edwards and Johnson-Stacer to nonlinear tube reptation models.

This class of systems describes nonlinear dissipative elastic models with the nonlinear term produced by neo-Hookean type stress–strain relationships. In the present work, we use an analysis based in part on the results of H.T. Banks, D.S. Gilliam and V.I. Shubov on the existence and uniqueness of the weak solutions to show that these systems generate a “strong” dynamical system also. More importantly, we are able to prove the existence of a compact “strong” global attractor. Finally, we make several comments concerning the regularity of this attractor, and present some examples.}, number={5}, journal={NONLINEAR ANALYSIS-THEORY METHODS & APPLICATIONS}, author={Pinter, GA}, year={2003}, month={May}, pages={653–668} } @article{banks_pinter_2003, title={Maxwell-systems with nonlinear polarization}, volume={4}, ISSN={["1468-1218"]}, DOI={10.1016/S1468-1218(02)00074-3}, abstractNote={We establish well-posedness results for a model describing the propagation of high-intensity electromagnetic waves in a nonlinear medium.
