[gpaw-users] Field enhancement

[Tuomas Rossi]

Hi,

The field enhancement is calculated as the total electric field strength 
divided by the incident electric field strength. In the case of a delta 
kick, the incident electric field strength is proportional to the kick 
strength. In the assumed linear response regime the field enhancement 
should not depend on the used kick strength.

Best,
Tuomas
