Shielding at a distance due to anomalous resonance in superlens with eccentric core
Sanghyeon Yu, Mikyoung Lim
A cylindrical plasmonic structure with a concentric core exhibits an anomalous localized resonance which results in cloaking effects. Here we show that, if the structure has an ecc…

Characterization of the gradient blow-up of the solution to the conductivity equation in the presence of adjacent circular inclusions
Mikyoung Lim, Sanghyeon Yu
We consider the conductivity problem in the presence of adjacent circular inclusions having arbitrary constant conductivity. When two inclusions get closer and their conductivities…
