Design of thin-film photonic metamaterial Lüneburg lens using analytical approach.
We design an all-dielectric Lüneburg lens as an adiabatic space-variant lattice explicitly accounting for finite film thickness. We describe an all-analytical approach to compensate for the finite height of subwavelength dielectric structures in the pass-band regime. This method calculates the effective refractive index of the infinite-height lattice from effective medium theory, then embeds a ...
متن کاملA Systematic Approach to Photonic Crystal Based Metamaterial Design
Photonic crystal design procedure for negative refraction has so far been based on trial and error. In this paper, for the first time, a novel and systematic design procedure based on physical and mathematical properties of photonic crystals is proposed to design crystal equi-frequency contours (EFCs) to produce negative refraction. The EFC design is performed by the help of rectangular stair-c...
متن کاملDesign of an acoustic metamaterial lens using genetic algorithms.
The present work demonstrates a genetic algorithm approach to optimizing the effective material parameters of an acoustic metamaterial. The target device is an acoustic gradient index (GRIN) lens in air, which ideally possesses a maximized index of refraction, minimized frequency dependence of the material properties, and minimized acoustic impedance mismatch. Applying this algorithm results in...
متن کاملProposal for new method to design all-dielectric photonic meta- materials using an analytical approach
We propose a new analytical approach to the study of all-dielectric metamaterials allowing the prediction of the optical index maps and the required hole drilling distributions making light follow prescribed paths. The method will be applied to proof-of-concept structures based on the silicon-on-insulator technology. Light propagation will be studied using FDTD simulation to verify light trajec...
متن کاملPhotonic magnetic metamaterial basics
In the present study, we provide a detailed analysis for the study of photonic metamaterials. We demonstrate the polarization and orientation dependent transmission response of split ring resonators at the infrared and visible band. We provided optical measurements only for one case, in which electric component of the incident field was coupled to planar split ring resonator array. We consecuti...
