Viscoelastic wave test function

  1. Feb 25, 2013 #1

    I am writing up (for some other students) our lab's inversion method for viscoelastic media. I want to use some test functions for simple illustrations, side by side with the actual inverted images.

    I can write simple test functions for elastic waves that come out perfectly -- all storage no loss -- along the lines of v(i,j) = cos(i+j). I can't figure out a good test function for something viscoelastic however.

    Can anyone suggest a test function that would produce a result with storage and loss. Or if this is not so simple to do, can anyone say anything about why? Obviously I've got a gap here.

    Many thanks,
