How to add material (const_eps or file_) with substrate command #158

Open shastrirahul opened 6 years ago

shastrirahul commented 6 years ago

I am trying to use substrate command with th following code

LATTICE VECTOR 0.2 0 VECTOR 0.0 0.2 ENDLATTICE

SUBSTRATE 0.0 MATERIAL FILE_audata.dat -0.03 VACUUM ENDSUBSTRATE

Showing error " could not find material MATERIAL FILE_audata.dat in any matprop file (aborting)"

I have the tabulated material data named "audata.dat". Can you resolve this issue.

Thanks for this report. Support for implicit dielectric substrates is fully implemented for electrostatic problems, but for nonzero-frequency problems it is a work in progress that is not quite ready for release. I am actively working on this and hope to have it ready soon.

Thank you again for your reply. I want a system consists of infinite Au-mirror with small Au-sphere of given diameter separated by some distance. I have tried the surface command to construct the geometry but not able to reproduce the results.Can you provide me an efficient commands in order to build the geometry. I have attached codes and geometry that I have used.

Thanking you in anticipation

Hi Homer, I was wondering if you have any update on this issue? Did you get around to implement the implicit substrates for nonzero-frequency problems (I'm mainly interested in scuff-scatter) yet? I noticed that if you include a substrate in the scuffgeo files, it does not raise any errors or warning but it just seems to be ignored. Thanks, Michel
