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…
On surface polariton resonance and its curvature concentration effects from 3D elastic nanorods
Youjun Deng, Hongyu Liu, Wanjing Tang +1
This paper investigates surface polariton resonance (SPR) in three-dimensional elastic metamaterials with nanorod geometry. The primary motivation is to surpass the physical limita…
Mathematical theory on multi-layer high contrast acoustic subwavelength resonators
Youjun Deng, Lingzheng Kong, Hongjie Li +2
Subwavelength resonance is a vital acoustic phenomenon in contrasting media. The narrow bandgap width of single-layer resonator has prompted the exploration of multi-layer metamate…
Optimal estimate of electromagnetic field concentration between two nearly-touching inclusions in the quasi-static regime
Youjun Deng, Hongyu Liu, Liyan Zhu
We investigate the electromagnetic field concentration between two nearly-touching inclusions that possess high-contrast electric permittivities in the quasi-static regime. By usin…
