Periodicity (Floquet?) conditions on a nanowire-based device

Please login with a confirmed email address before reporting spam

Hello,

I am developing a device composed of nanowires (vertical metal cylinders) embedded in a polymer matrix, topped with metal electrodes (shown in gold in the illustration).

To facilitate calculations, I am simulating on a 2D model.

I would like to: - draw half-spheres to represent the cylinders in a top view (I will not draw the electrodes in this case) - use periodicity conditions (why not Floquet conditions?) at the half-spheres to duplicate them in one direction.

-> What periodicity conditions could I use? How are they configured?

Thank you in advance, have a great day!

To clarify (for those like me who do not normally work in your field), can you explain a little more about the physics you want to model? I'm guessing that this is for some kind of electromagnetic application. Electrostatics? Microwaves? A grid of probes involving electro- or bio-chemistry? What do you actually want to investigate & compute? Your options in Comsol Multiphysics and the best/correct choices of boundary conditions (among many other settings), will generally depend on the physics you are studying.
