Design of invisibility cloaks with an open tunnel.
In this paper we apply the methodology of transformation optics for design of a novel invisibility cloak which can possess an open tunnel. Such a cloak facilitates the insertion (retrieval) of matter into (from) the cloak's interior without significantly affecting the cloak's performance, overcoming the matter exchange bottleneck inherent to most previously proposed cloak designs.We achieve thi...
متن کاملFe b 20 08 A Rigorous Analysis of High Order Electromagnetic Invisibility Cloaks ∗
There is currently a great deal of interest in the invisibility cloaks recently proposed by Pendry et al. that are based in the transformation approach. They obtained their results using first order transformations. In recent papers Hendi et al. and Cai et al. considered invisibility cloaks with high order transformations. In this paper we study high order electromagnetic invisibility cloaks in...
متن کاملCreating the Open Wordnet Bahasa
This paper outlines the creation of the Wordnet Bahasa as a resource for the study of lexical semantics in the Malay language. It is created by combining information from several lexical resources: the French-English-Malay dictionary FEM, the KAmus MelayuInggeris KAMI, and wordnets for English, French and Chinese. Construction went through three steps: (i) automatic building of word candidates;...
متن کاملIsotropic nonmagnetic flat cloaks degenerated from homogeneous anisotropic trapeziform cloaks.
We propose a novel kind of trapeziform cloak requiring only homogeneous anisotropic materials. Large-scale flat cloaks can be degenerated from the general trapeziform cloak with PEC inner boundary, and be realized by isotropic nonmagnetic materials for optical frequencies with controlled index profiles and improved invisibility. With the support of PEC inner boundary, large vehicles and objects...
متن کاملRemote acoustic cloaks
Due to the correspondence of the acoustic equations to Maxwell’s equations of one polarization in two dimensions, we exploit theoretically the acoustic counterpart of the recently proposed remote invisibility cloak. The cloak consists of a circular cylindrical core with designed bulk moduli, and an “anti-object” embedded inside a shell with anisotropic mass densities. The material parameters of...
