Impedance effect on imaging of far-field hyperlens with geometrically increasing layer thicknesses
The hyperlens with flat dispersion curve and geometrically growing layer thicknesses are designed to project an object to the far field beyond the diffraction limit. Three hyperlens structures (two are our hyp...

Manipulating light flow with one-dimensional photonic crystals of an electromagnetically induced transparency medium
The band structures and equifrequency contours of one-dimensional photonic crystals (PCs), which consist of an electromagnetically induced transparency (EIT) medium and a common dielectric medium, can be drama...
