A Fast Butterfly-compressed Hadamard-Babich Integrator for High-Frequency Helmholtz Equations in Inhomogeneous Media with Arbitrary Sources
Yang Liu, Jian Song, Robert Burridge +1
We present a butterfly-compressed representation of the Hadamard-Babich (HB) ansatz for the Green's function of the high-frequency Helmholtz equation in smooth inhomogeneous media.…

Time- vs. frequency- domain inverse elastic scattering: Theory and experiment
Xiaoli Liu, Jian Song, Fatemeh Pourahmadian +1
This study formally adapts the time-domain linear sampling method (TLSM) for ultrasonic imaging of stationary and evolving fractures in safety-critical components. The TLSM indicat…
