Super-resolution Imaging of the Graded Photonic Crystal with Negative Refraction
In this paper, super-resolution imaging and negative refraction by a two-dimensional (2D) triangular lattices graded photonic crystal (GPC) were studied. The graded photonic crystal (GPC) was obtained by varying the radius in each row so that its effective refractive index changes along the transverse direction. By using Plane Wave Expansion (PWE) method and Finite-Difference Time-Domain (FDTD)...
متن کاملAntireflection gratings for a photonic-crystal flat lens.
A dielectric structure with effective permittivity and permeability close to -1 operating for propagative waves at optical wavelengths is proposed. This structure is a two-dimensional photonic crystal with refractive index -1, coated by appropriate antireflection gratings. Numerical simulations involving a flat lens made of this optimized crystal illustrate the improvements that antireflection ...
متن کامل3D Object Super-Resolution
We consider the problem of scaling deep generative shape models to high-resolution. To this end, we introduce a novel method for the fast up-sampling of 3D objects in voxel space by super-resolution on the six orthographic depth projections. We demonstrate the training of object-specific super-resolution CNNs for depth maps and silhouettes. This allows us to efficiently generate high-resolution...

متن کاملImage resolution depending on slab thickness and object distance in a two-dimensional photonic-crystal-based superlens
Based on the exact numerical simulation and physical analysis, we have demonstrated all-angle single-beam left-handed behavior and superlens for both TE and TM modes in a two-dimensional coated photonic crystals. The imaging behaviors by two-dimensional photonic-crystal-based superlens have been investigated systematically. Good-quality images and focusing, with relative refractive index of -1,...
