Exact high-order GPT cancellation in noncircular multilayers
Youjun Deng, Hongyu Liu, Longyue Tao
This paper is concerned with exact high-order generalized polarization tensor (GPT) cancellation in two-dimensional noncircular multilayers with finite positive isotropic coating c…
Locating multiple magnetized anomalies by geomagnetic monitoring
Rongliang Chen, Youjun Deng, Yang Gao +2
The presence of magnetized anomalies in the shell of the Earth interrupts its geomagnetic field. We consider the inverse problem of identifying the anomalies by monitoring the vari…
Elastostatics with multi-layer metamaterial structures and an algebraic framework for polariton resonances
Youjun Deng, Lingzheng Kong, Hongyu Liu +1
Multi-layer structures are ubiquitous in constructing metamaterial devices to realise various frontier applications including super-resolution imaging and invisibility cloaking. In…
Optimal estimate of field concentration between multiscale nearly-touching inclusions for 3-D Helmholtz system
Youjun Deng, Yueguang Hu, Hongyu Liu +1
We are concerned with the field concentration between two nearly-touching inclusions with high-contrast material parameters, which is a central topic in the theory of composite mat…
On plasmon modes in multi-layer structures
Xiaoping Fang, Youjun Deng
In this paper, we consider the plasmon resonance in multi-layer structures. The conductivity problem associated with uniformly distributed background field is considered. We show t…
Plasmon resonances of nanorods in transverse electromagnetic scattering
Youjun Deng, Hongyu Liu, Guang-hui Zheng
Plasmon resonance is the resonant oscillation of conduction electrons at the interface between negative and positive permittivity material stimulated by incident light, which forms…
