Singular perturbation of reduced wave equation and scattering from an embedded obstacle
Hongyu Liu, Zaijiu Shang, Hongpeng Sun +1
We consider time-harmonic wave scattering from an inhomogeneous isotropic medium supported in a bounded domain (). {In a subregion , the…

Enhanced Near-cloak by FSH Lining
Hongyu Liu, Hongpeng Sun
We consider regularized approximate cloaking for the Helmholtz equation. Various cloaking schemes have been recently proposed and extensively investigated. The existing cloaking sc…

Enhanced Approximate Cloaking by SH and FSH Lining
Jingzhi Li, Hongyu Liu, Hongpeng Sun
We consider approximate cloaking from a regularization viewpoint introduced in [13] for EIT and further investigated in [12] [17] for the Helmholtz equation. The cloaking schemes i…
