05.12.2007 | Ira Didenkulova “Traveling wave solution in strongly inhomogeneous media”, 18:00 (1.5 hr). |
The existence of traveling “non-reflective” wave solutions of a linear one-dimensional | |
wave equation, with variable speed, is studied. Similar to waves propagating in homogeneous | |
and weakly inhomogeneous media, such solutions can be found provided the variable wave speed | |
satisfies certain conditions. Non-reflective waves with variable amplitudes and phases | |
traveling in opposite directions can be found as solutions of the Cauchy problem. | |
It is shown that the solution exists on finite time only. | |
