Comsol 4.2 Tutorial Part_3.avi

This tutorial is the last one on a series of 3. Shows how to build a model step by step. Electromagnetic waves scattering off of a nano sphere. Use of work planes and revolve. Importing material properties as a function of wavelength. PML boundary conditions. Mapped mesh.

If you can help me I will be grateful. If you want to see my model just mail me gustavolsilvano@gmail.com.

Thanks.

@gustavolsilvano I am a full time graduate student. I would like to look at your model but being realistic, I don't know when I will have time since I am currently working on three different projects. My best advice is to search the forums in Comsol's website, they have helped me in the past.

Really Great, thank you so much.

Would you recommend some books for Comsol, many thanks

@hanhan447777 I learned the basics by trial and error and reading forums. Then I took an intensive two day training. COMSOL offers free 2 hour training (in the L.A. area) every time there is a new version out. That might be helpfull to break the ice.

Hi there. Your videos were very interesting, and helped me in my models. But I'm having a problem when trying to simulate a nanodiopole with a lumped port between them. What I seek is the lumped port impedance and the s-parameter. When I simulate a dipole in meters scale and with MHz frequency, it leads me the right answer, but when I use a nano scale and THz, then it leads me to a very small input impedance. For the boundary condition, I just use a sphere with the scattering codition.
