triangular lattice hfss master slave
Hi all,
I've found out how to fix the problem for master/slave boundaries in skewed arrays. Instead of using a single master/slave at opposite faces of the airbox, it is necessary to use two masters on one face (with different widths, in order to reproduce the desired shift of surrounding unit cells) and two slaves at the other face (the order of slaves must be inverted respect to the masters). See the file to understand what I mean.
Now I have another problem. Since I need to simulate my unit cell including an amplifier inside the structure (there are two lumped ports in the middle of the cell), I need to simulate it with an Ansoft Designer Dynamic link. Thus, in order to represent the incident and the re-radiated waves, I need to use Floquet ports instead of radiation or PMLs at the upper and lower faces of the airbox, as u can see in the file (one port(1) to excite the receiving antenna and the other one (2) associated to the field which is reradiated by the orthogonal transmitting antenna). These Floquet ports will be appropriately connected to some microwave ports in Ansoft Designer, where I push the excitation to the HFSS model.
Now, after the validate check in HFSS I get the following error messages:
[error] Port 'FloquetPort1': The exterior boundary of the faces for a Floquet Port must consist of pairs of parallel and equal length segments, displaced from each other by an integer linear combination of the lattice vectors.
[error] Port 'FloquetPort2': The exterior boundary of the faces for a Floquet Port must consist of pairs of parallel and equal length segments, displaced from each other by an integer linear combination of the lattice vectors.
It's evident that the definition of the Floquet Ports doesn't match the lattice definition obtained by the particular use of the periodic boundaries.
Does anybody have any idea or know how to set Floquet ports correctly for this case?
