Wigner-Smith Time Delay Matrix for Acoustic Scattering: Computational Aspects

Utkarsh R. Patel, Yiqian Mao, Jack Hamel +1

The Wigner-Smith (WS) time delay matrix relates an acoustic system's scattering matrix to its wavenumber derivative. The entries of the WS time delay matrix can be expressed in ter…
