I was wondering; do these simulation tools stay in the realm of classical EM or can they account for (not explicitly modeled) quantum effects? For example, if you model two different types of metals in contact, will you be able to 'see' charge transfer and the developing of a contact potential?
Hi, I am a german master student and I am really wondering about the magnetic boundary condition in CST high frequency simulations. It is a recommended setting for the simulation of microstrips with waveguides to support the QTEM mode. But when setting a magnetic boundary condition (Ht = 0) and checking the H-field with a field monitor, the tangential part of H ist not zero on the boundaries (nor is the normal elctric flux)! So the magnetic boundary is not adhered to. This really confuses me. Maybe you could explain this and why one would set magnetic boundaries for a microstrip in the first place. I would be very grateful, if you did
If you use magnetic boundary, then H_t = 0 at the boundary. Maybe the field monitor is misleading, would need to see the plot. The recommendation is not a must. You can also define an "inner" waveguide port which does not touch a boundary.
Superb video linking all various methods to calculate capacitance!
Andreas nice work with these videos! I look forward to studying these as I use CST.
Thanks, good to see this. Also I think that CST interface is much easier than Ansys that I use. Hopefully I will transition to CST one day ;-)
Haven't used those EStatic solvers. Are they a lot faster than the fullwave?
Yes, they are much faster than fullwave as they only solve a potential equation.

It purely classical EM. No quantum effects, no contact potential.
Andreas, would you by any chance be willing to make the partial RLC files available for download so we can see you setup in detail?
I can share the files, do you want me to drop them somewhere ?

Thanks for the video. Is it possible to know which post processing template you used (@3mn30) and how this one is configured?
One is the Y-Parameter template, the other is the Z-Parameter template. I have another video about RLC from S-Parameters in the channel
