but how?

Hi, I think I have been having this question for some time now. What is the difference between tensor calculus and linear algebra? Both seem to make frequent use of matrices, but they seem to be different subject matter. Can anyone please enlighten me on this issue?

Hi, thank you very much! I think I agree with you that the charge density here refers to the free charge. The author's point of mentioning the charge relaxation is that in metals Gauss's law can be considered as divergence of electric field equals zero, since any charge would exponentially...

I have been using Born and Wolf's Principles of Optics for a project but I don't quite understand the concept of charge relaxation in metals (eq.6, P736 of 7th ed). The author used Ampere-Maxwell's law and Gauss's law to derive a differential equation involving the time differentiation of charge...

Thank you. I see. I guess i'll just look for alternatives.

I've been trying to search for this seminal paper on EM waves in stratified media. 'Investigations on the propagation of sinusoidal electromagnetic waves in stratified media', by F. Abeles Ann. Phys. (Paris) 5, 596, 706 (1950). I cannot find it in any database. Can anyone please tell me...

hi. i got the same problem. i don't know why your question has become my assignment question and how my prof came across it.

nice explanation

oh. my goodness. does that mean each time you do the simulation you get only the result for a single frequency? i haven't anticipated such difficulty with comsol simulation. i am actually a beginner doing light scattering by metallic nanoparticles. and i pretty much want to find the spectra of...

BTW. do you have any idea about whether PML can be implemented in transient propagation mode? thank you very much.

hi dude. i have one question. do you know how to use the dielectric function of metal from the material library to perform the scattering simulation?

thanks for the update man!

i think maybe relocate the PML further from the particle helps. the evanescent tail of the surface plasmon should be avoid from extending into the PML.
