Dear all,
I am trying to simulate the variable-sized patch in CST, to get the phase-size S curve. I already did this in HFSS, but want to check the results using CST. In HFSS i am using the master/slave BCs for the unit cell and one floquet port above the patch. I want to see the reflection phase at or above the patch.
But in CST, now i am using the following BCs: Xmin, Xmax, Ymin and Ymax as "unit cell", Zmin as "electric (Et=0)" (which is ground), and Zmax as "open (add space)". And i set the distance to reference plane as -13.5 (seems just above the patch). What's the Z value of this reference plane? And i cann't run the simulation using Frequency domain solver. It is said "initialization database failed".
Any hint please? Thanks in advance.
Attached is the CST file:
