Metamaterials and Negative Refractive Index [PDF]
Science, 2004 Recently, artificially constructed metamaterials have become of considerable interest, because these materials can exhibit electromagnetic characteristics unlike those of any conventional materials. Artificial magnetism and negative refractive index are two specific types of behavior that have been demonstrated over the past few years, illustrating the

Modification of Low Refractive Index Polycarbonate for High Refractive Index Applications [PDF]
International Journal of Polymer Science, 2009 Polycarbonates and polythiourethanes are the most popular materials in use today, for optical applications. Polycarbonates are of two types which fall in the category of low refractive index and medium refractive index.

Uniform Refraction in Negative Refractive Index Materials [PDF]
Journal of the Optical Society of America A, 2015 We study the problem of constructing an optical surface separating two homogeneous, isotropic media, one of which has a negative refractive index. In doing so, we develop a vector form of Snell's law, which is used to study surfaces possessing a certain ...

Refractive index sensing with optical bound states in the continuum. [PDF]
Optics Express, 2020 We consider refractive index sensing with optical bounds states in the continuum (BICs) in dielectric gratings. Applying a perturbative approach we derived the differential sensitivity and the figure of merit of a sensor operating in the spectral ...

Design of Ultra-Narrow Band Graphene Refractive Index Sensor
Italian National Conference on Sensors, 2022 The paper proposes an ultra-narrow band graphene refractive index sensor, consisting of a patterned graphene layer on the top, a dielectric layer of SiO2 in the middle, and a bottom Au layer. The absorption sensor achieves the absorption efficiency of 99.

Ray Tracing Method of Gradient Refractive Index Medium Based on Refractive Index Step
Applied Sciences, 2021 For gradient refractive index media with large refractive index gradients, traditional ray tracing methods based on refined elements or spatial geometric steps have problems such as low tracing accuracy and efficiency.

Temperature‐Controlled Optical Activity and Negative Refractive Index
Advanced Functional Materials, 2021 Chiral media exhibit optical activity, which manifests itself as differential retardation and attenuation of circularly polarized electromagnetic waves of opposite handedness.
