Gaussian Beams

What do bats and oil companies have in common? Both use active sensing methods (echolocation) in pursuit of their objectives—dinner or oil reserves. Recently, the method of Gaussian beams has become a promising alternative for asymptotic solutions to the wave equations in place of the traditional methods based on geometric optics for finding approximate short-time solutions.
