Uniqueness in inverse diffraction grating problems with infinitely many plane waves at a fixed frequency
Xiaoxu Xu, Guanghui Hu, Bo Zhang +1
This paper is concerned with the inverse diffraction problems by a periodic curve with Dirichlet boundary condition in two dimensions. It is proved that the periodic curve can be u…
Uniqueness to inverse acoustic scattering from coated polygonal obstacles with a single incoming wave
Guang-Hui Hu, Manmohan Vashisth
It is proved that a connected polygonal obstacle coated by thin layers together with its surface impedance function can be determined uniquely from the far field pattern of a singl…
Uniqueness for time-dependent inverse problems with single dynamical data
Ibtissem Ben Aïcha, Guanghui Hu, Manmohan Vashisth +1
In this work, we investigate the shape identification and coefficient determination associated with two time-dependent partial differential equations in two dimensions. We consider…
Inverse time-harmonic electromagnetic scattering from coated polyhedral scatterers with a single far-field pattern
Guang-Hui Hu, Manmohan Vashisth, Jiaqing Yang
It is proved that a convex polyhedral scatterer of impedance type can be uniquely determined by the electric far-field pattern of a non-vanishing incident field. The incoming wave…
Stability inequality for a semilinear elliptic inverse problem
Mourad Choulli, Guanghui Hu, Masahiro Yamamoto
We establish a logarithmic stability inequality for the inverse problem of determining the non linear term, appearing in a semilinear BVP, from the corresponding Dirichlet-to-Neuma…
Inverse scattering for the one-dimensional Helmholtz equation with piecewise constant wave speed
Sophia Bugarija, Peter C. Gibson, Guanghui Hu +2
This paper analyzes inverse scattering for the one-dimensional Helmholtz equation in the case where the wave speed is piecewise constant. Scattering data recorded for an arbitraril…
