Simulation of EELS spectra #155

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
It seems easy to simulate the results of electron-energy-loss spectroscopy 
(EELS) with the DDA. The trick is to replace the plane incident wave in the DDA 
by the field of a swift electron.

It is described in N.W. Bigelow, A. Vaschillo, V. Iberi, J.P. Camden, and D.J. 
Masiello, “Characterization of the electron- and photon-driven plasmonic 
excitations of metal nanorods,” ACS Nano 6, 7497–7504 (2012).

The corresponding proof-of-principle code "e-DDA" based on DDSCAT 7.1 is freely 
available at 
http://faculty.washington.edu/masiello/Masiello_Group_Website/e-DDA.html

This may be connected with issue 149, as it also requires modification of the 
incident field to unusual (singular) one.

To make EELS simulations practical and efficient the simulation of spectra 
probably need to be considered - issue 35.

It is extremely interesting to combine EELS with surface mode - issue 101. The 
first question, what would be the field of the electron in such setting.
