“Distribution of resonances in scattering by thin barriers“, by Jeff Galkowski, Department of Mathematics, Stanford University.

The lecture:

“A solution to the wave equation for the transparent obstacle with speed 0.5. Damping is placed near the boundary of what is plotted to prevent spurious reflections.”

“A solution to the wave equation for the transparent obstacle with speed 2. Damping is placed near the boundary of what is plotted to prevent spurious reflections.”
