textile shielding simulation

[blindwidow]

Hi there,

I want to simulate the shielding properties of some textile fabrics including conducting threads in it. In laboratory conditions, the fabrics are placed in the middle of two identical antennas and the loss is measured through one of the antennas. Shielding parameters are calculated based on this measurement. But I also want to simulate the process. Does HFSS or CST capable of doing such simulation?

Thank you,

I can only speak for HFSS: if you want to simulate the same environment (including the antennas etc), then you would need a huge amount of RAM... maybe with the newer IE solver you could get there, but with less accuracy.

If you are okay with some abstraction, maybe something like a waveguide environment, then HFSS could definitively be your weapon of choice here. The main difference is that HFSS is a FEM solver (frequency domain) whereas CST is a FIT (somewhat like FDTD) solver, ie in the time domain. So, if you want to simulate the absorption or reflection over a frequency span, I think HFSS is definitively capable of doing the job.
