Spectral properties of the Neumann-Poincaré operator and cloaking by anomalous localized resonance for the elasto-static system
Kazunori Ando, Yong-Gwan Ji, Hyeonbae Kang +2
We first investigate spectral properties of the Neumann-Poincaré (NP) operator for the Lamé system of elasto-statics. We show that the elasto-static NP operator can be symmetrized…

Plasmon resonance with finite frequencies: a validation of the quasi-static approximation for diametrically small inclusions
Kazunori Ando, Hyeonbae Kang, Hongyu Liu
We study resonance for the Helmholz equation with a finite frequency in a plasmonic material of negative dielectric constant in two and three dimensions. We show that the quasi-sta…

Analysis of plasmon resonance on smooth domains using spectral properties of the Neumann-Poincaré operators
Kazunori Ando, Hyeonbae Kang
We investigate in a quantitative way the plasmon resonance at eigenvalues and the essential spectrum (the accumulation point of eigenvalues) of the Neumann-Poincaré operator on smo…
