Optimal estimates and asymptotics for the stress concentration between closely located stiff inclusions
Hyeonbae Kang, Hyundae Lee, KiHyun Yun
If stiff inclusions are closely located, then the stress, which is the gradient of the solution, may become arbitrarily large as the distance between two inclusions tends to zero.…
Construction of conformal mappings by generalized polarization tensors
Hyeonbae Kang, Hyundae Lee, Mikyoung Lim
We present a new systematic method to construct the conformal mapping from outside the unit disc to outside of a simply connected domain using the generalized polarization tensors.…
Bounds on the size of an inclusion using the translation method for two-dimensional complex conductivity
Hyeonbae Kang, Kyoungsun Kim, Hyundae Lee +2
The size estimation problem in electrical impedance tomography is considered when the conductivity is a complex number and the body is two-dimensional. Upper and lower bounds on th…
Cloaking due to anomalous localized resonance in plasmonic structures of confocal ellipses
Daewon Chung, Hyeonbae Kang, Kyoungsun Kim +1
If a core of dielectric material is coated by a plasmonic structure of negative dielectric material with non-zero loss parameter, then anomalous localized resonance may occur as th…
Coated inclusions of finite conductivity neutral to multiple fields in two dimensional conductivity or anti-plane elasticity
Hyeonbae Kang, Hyundae Lee
We consider the problem of neutral inclusions for two-dimensional conductivity and anti-plane elasticity. The neutral inclusion, when inserted in a matrix having a uniform field, d…
Anomalous localized resonance using a folded geometry in three dimensions
Habib Ammari, Giulio Ciraolo, Hyeonbae Kang +2
If a body of dielectric material is coated by a plasmonic structure of negative dielectric material with nonzero loss parameter, then cloaking by anomalous localized resonance (CAL…
