High-OrderWave Equation for Thermal Transport Induced by Ultrashort Laser Pulses
Magdalena Pelc, Janina Marciak-Kozlowska and Miroslwa Kozlowski

In this paper the high-order partial differential equation (PDE) for thermal phenomena is discussed. It is shown that the third-order PDE, high-order wave equation for thermal phenomena describes the strongly damped thermal wave. The solution of the third-order wave equation is completely attenuated for x/l > 1, where l is the mean free path.
