[Wien] Aloof spectra/dielectric for a surface

[L. D. Marks]

I'd like to look for low-energy surface plasmons for a surface, either via
an aloof spectroscopy calculation (i.e. electron beam outside the surface)
or the same information can be (kind-of) extracted from the dielectric
function. Since this would be for a surface slab, a really dense k-point
mesh would take forever. I'd be interested in suggestions as to what I
could get away with as well as suggestions about how to seperate the bulk
and surface contributions (which might not be trivial).
