S-Parameter SymmetriesSimulation: Solver Start Simulation S-parameter listThis dialog offers the possibility of defining specific symmetries concerning the reflection and transmission behavior of propagating signals based on some given structure symmetries. To save simulation time, the transient solver will perform only the minimum number of necessary simulation runs, all the remaining results (S-parameter as well as time signals) are copied due to the defined symmetry conditions.Symmetry list Here, all occurring port combinations are listed in the reference column, representing either the reflection behavior at one port (e.g., 1,1) or the transmission behavior of one port to another (e.g., 2,1). The latter is assumed to be identical in both directions (e.g., 2,1 and 1,2) and thus appear only once in the list. By selecting several rows, the desired symmetry condition can be set using the Set symmetry button. All defined symmetry sets are then displayed in the symmetry column highlighted in different colors marking the port combinations that belong together. Set symmetry Pressing this button defines a symmetry set for all selected port combinations in the symmetry list. It is necessary to select at least two rows to define a valid set. Reset Pressing this button deletes all previously made symmetry entries only for the selected rows, all other settings remain. Reset all This button resets the complete symmetry list, i.e., all previously made symmetry entries will be deleted. OK Accepts the input and closes the dialog. Cancel Closes this dialog box without performing any further action. Help Shows this help text.
