Hybrid topological photonic crystals
Yanan Wang, Hai-Xiao Wang, Li Liang +8
Photonic topological phases offering unprecedented manipulation of electromagnetic waves have attracted much research interest which, however, have been mostly restricted to a sing…
Electromagnetic Energy Density in Hyperbolic Metamaterials
Afshin Moradi, Pi-Gang Luan
We derive the energy density associated with an electromagnetic wave passing through a hyperbolic metamaterial (HMM). Both types of HMMs are studied. By considering a dispersive an…
Lagrangian description and Hamiltonian density for the electrodynamics of dispersive metamaterials
Pi-Gang Luan
The Lagrangians and dissipation functions are proposed for use in the electrodynamics of the double-negative and chiral metamaterials with finite loss. The double-negative metamate…
On the possibility of superluminal energy propagation in a hyperbolic metamaterial of metal-dielectric layers
Pi-Gang Luan, Jie-Luen Wu
The energy propagation of electromagnetic fields in the effective medium of a one-dimensional photonic crystal consisting of dielectric and metallic layers is investigated. We show…
Coriolis Force Induced Quantum Hall Effect for Phonons
Yao-Ting Wang, Pi-Gang Luan, Shuang Zhang
A two-dimensional mass-spring system with Honeycomb lattice for mimicking phononic quantum Hall effect is proposed. Its band structure shows the existence of Dirac cones and unconv…
Influences of source displacement on the features of subwavelength imaging of a photonic crystal slab
Pi-Gang Luan, Chen-Yu Chiang, Hsiao-Yu Yeh
In this paper we study the characteristics of subwavelength imaging of a photonic crystal (PhC) superlens under the influence of source displacement. For square- and triangular-lat…
