Plasmon resonances of nanorods in transverse electromagnetic scattering
Youjun Deng, Hongyu Liu, Guang-hui Zheng
Plasmon resonance is the resonant oscillation of conduction electrons at the interface between negative and positive permittivity material stimulated by incident light, which forms…
Invisibility enables super-visibility in electromagnetic imaging
Youzi He, Hongjie Li, Hongyu Liu +1
This paper is concerned with the inverse electromagnetic scattering problem for anisotropic media. We use the interior resonant modes to develop an inverse scattering scheme for im…
Two unique Identifiability results for inverse scattering problems within polyhedral geometries
Xinlin cao, Huaian Diao, Hongyu Liu +1
We consider the unique determinations of impenetrable obstacles or diffraction grating profiles in by a single far-field measurement within polyhedral geometries. We…
Stable determination of an elastic medium scatterer by a single far-field measurement and beyond
Zhengjian Bai, Huaian Diao, Hongyu Liu +1
We are concerned with the time-harmonic elastic scattering due to an inhomogeneous elastic material inclusion located inside a uniformly homogeneous isotropic medium. We establish…
Simultaneous recoveries for semilinear parabolic systems
Yi-Hsuan Lin, Hongyu Liu, Xu Liu +1
In this paper, we study inverse boundary problems associated with semilinear parabolic systems in several scenarios where both the nonlinearities and the initial data can be unknow…
Surface concentration of transmission eigenfunctions
Yat Tin Chow, Youjun Deng, Hongyu Liu +1
The transmission eigenvalue problem is a type of non-elliptic and non-selfadjoint spectral problem that arises in the wave scattering theory when invisibility/transparency occurs.…
