Analysis of a finite element DtN method for scattering resonances of sound hard obstacles
Yingxia Xi, Bo Gong, Jiguang Sun
Scattering resonances have important applications in many areas of science and engineering. They are the replacement of discrete spectral data for problems on non-compact domains.…

A finite element contour integral method for computing the resonances of metallic grating structures with subwavelength holes
Yingxia Xi, Junshan Lin, Jiguang Sun
We consider the numerical computation of resonances for metallic grating structures with dispersive media and small slit holes. The underlying eigenvalue problem is nonlinear and t…

The anisotropic interior transmission eigenvalue problem with a conductive boundary
Victor Hughes, Isaac Harris, Jiguang Sun
In this paper, we study the transmission eigenvalue problem for an anisotropic material with a conductive boundary. We prove that the transmission eigenvalues for this problem exis…
