Wigner-Smith Time Delay Matrix for Acoustic Scattering: Theory and Phenomenology
Utkarsh R. Patel, Yiqian Mao, Eric Michielssen
The Wigner-Smith (WS) time delay matrix relates a lossless system's scattering matrix to its frequency derivative. First proposed in the realm of quantum mechanics to characterize…
