10 Nov 2006. Vol 314, Issue 5801. pp. 977 - 980. DOI: 10.1126/science.1133628. Abstract. A recently published theory has suggested that a cloak of invisibility is in principle possible, at least over a narrow frequency band.
Metamaterial cloaking is the usage of metamaterials in an invisibility cloak. This is accomplished by manipulating the paths traversed by light through a novel optical material. Metamaterials direct and control the propagation and transmission of specified parts of the light spectrum and demonstrate the potential to render an object seemingly ...
Feb 1, 2024 Metamaterials are a class of artificial materials that have properties that do not exist in nature, making them ideal for a wide range of applications in engineering and science. One of the most exciting applications of metamaterials is in the development of cloaking devices, which can render objects invisible to the human eye.
Jun 19, 2014 Nature Communications - Cloaking of a range of stimuli have been demonstrated in various metamaterials recently. Here, the authors report mechanical cloaking in a pentamode structure,...
The Scattering cancellation technique is another familiar method to cloak an object with a metamaterial shell, where scattering from the object being cloaked is reduced to zero [17,18]. For that purpose, scattering cross-section (SCS) is used as a metric to judge the performance of the cloak. A good cloaking device maintains an SCS below one.
May 1, 2023 Metamaterial. Functionally graded material. 1. Introduction. Cloaking is a task that hides objects in a particular physical field, such as optical [1], electromagnetic [2], [3], and magnetic [4]. The device to accomplish the task can be termed an invisibility cloak.
17 November 2021. Article history. PDF. Split View. Annotate. Cite. Permissions. Abstract. The model of ideal fluid flow around a cylindrical obstacle exhibits a long-established physical picture, where originally straight streamlines are deflected over the whole space by the obstacle.
Cloaking, Metamaterial, FDTD, FEM, LC MTM. 1 Introduction. Recently, a novel approach to the design of electromagnetic structures has been proposed, in which the electromagnetic waves are controlled within a material by introducing a prescribed spatial variation in the constitutive parameters.
Metamaterial cloaking on the road to electromagnetic invisibility. Posted 3 years ago by Admin ASRMETA. Invisibility cloaking or cloaking devices refer to a piece of garment or a device that can render a human being utterly invisible to the naked eye. Although invisibility cloaks seem like a concept of science fiction, they are now a reality.
