modal Q-factor in FEKO CMA

Altair Forum User

Hi,

Has anyone furthered FEKO characteristic mode analysis (CMA) for 'modal Q factor' calculation (for individual modes and also considering all modes at specific frequencies of interest) after CM modes (and associated eigen values, modal significance, characteristic angle) are found in FEKO?

If so, this would be very helpful and would like to know how to setup for it, any specific article/paper?

Regards

Modal Q factors are not currently directly available in FEKO.
If you would like to perform your own Q factor calculations with FEKO extracted Z-matrices you can have look at the following paper:

Hi,

In this article, the expression of the Q factor contains the eigencurrents and eigenvalues .. at least this is what I undrestood so can you please explain me how to extract them
