The high resolution sampling methods for acoustic sources from multi-frequency far field patterns at sparse observation directions
Xiaodong Liu, Qingxiang Shi
This work is dedicated to novel uniqueness results and high resolution sampling methods for source support from multi-frequency sparse far field patterns. With a single pair of obs…

Uniqueness and modified Newton method for cracks from the far field patterns with a fixed incident direction
Jialei Li, Xiaodong Liu
We consider the inverse cracks scattering problems from the far field patterns with a fixed incident direction. We firstly show that the sound-soft cracks can be uniquely determine…
