Core-shell simulation and material size in nm
I am working on Ag core-Au shell nanoparticles and I am using DDSCAT+ software to simulate the extinction spectrum of the materials. I did follow the tutorial video on youtube and knew how to use the software. However, I have some questions as follow:
1) The materials size is at nm, but the measurement system in DDSCAT+ is either no unit or metric. Thus, what can I do to set up the nm-level size for 3-D model?
2) I am working on the core-shell formation in Blender, but I don’t know the proper way to design that structure. What I did was that I constructed two UV sphere meshes and I increased the thickness of one shape to form the shell. Is there any proper way to design a core-shell formation in Blender? All the parameters and screenshots are attached in this e-mail, so please take a look.
3) In the last step of simulation, the software has been running for about an hour and 30% of work has been done. I stopped the simulation to check the results, but the simulation is not complete and the near field could not be calculated (shown in the screenshots). Therefore, could you please let me know the normal amount of time that the simulation needs?
Thank you so much for your consideration and I am looking forward to hearing from you!
