I want to recognize and calculate R/Q for the Higher Order Modes (HOMs) in a multi-cell coupled accelerating structure. Although by plotting the E and B field components in radial, azimuthal and longitudinal direction, mode index (mnp) can be find out and can also calculate R/Q. But there are a large number of modes (below cut off frequency of the beam pipe) with complex patterns, it is very time consuming to analyze each mode (and there is a possibility of error also). Is there any VBA macro for this in CSTMWS? If yes, it will be a great help if some can share it with me.

With regards,

Shankar
