Activity points 8,630 τ = - dΦ / dω τ group delay Φ phase ω angular frequency see Matthaei, Young, and Jones for more details. I have seen it both with and without the negative sign. I am incertain about the convention. HFSS on-line help has additional information if you can get to the documentation.
