This is a very important method although you can't find eigenvectors often.

For example, in "scattering problems", which are usual in electromagnetics, eigenvalues are continuous. In the case,

for any , is an eigenfunction with eigenvalue:

So we look at problems where is not an eigenfunction.

where we need .
