Josh Innes Racist Caricature Jun 01, 2010 · The acoustic cloak is an important device, which can cloak an object from the detecting of sonar. Based on the concepts of complementary media and nonlinear coordination transformation, the generalized expressions for material parameters of the complementary medium-assisted external acoustic cloak with N-sided regular polygonal cross section are derived. cloak, a com plementa r y cloak is rst in troduced by usin g the trapezoid coordina te transf ormatio n. en an illusion device in terms of ano ther trapezoid coordina te transf ormatio n is Oct 24, 2013 · The cloak is constructed with six isosceles triangles of air with a refractive index of n 2 =1 and six isosceles triangles of glass with a refractive index of n 1 =1.78, as shown in Fig. 2a.
A kind of transformation media, which we shall call the “anti-cloak”, is proposed to partially defeat the cloaking effect of the invisibility cloak. An object with an outer shell of “anti-cloak” is visible to the outside if it is coated with the invisible cloak. Fourier-Bessel analysis confirms this finding by showing that external electromagnetic wave can penetrate into the interior
Conduction and convection are two fundamental methods of heat transfer, which are generally considered independent. We manage to unify them by coining…
second bearing may not rotate relative to the housing. The control arm also includes a first spring in the first portion of the housing and a second spring in the second portion of the housing. Rotation of the shaft in a first direction compresses both the first spring and the second spring and rotation of the

Two kinds of cloaks have been proposed: free-space cloaks, which can render objects in free space invisible to incident radiation, and carpet cloaks (or ground-plane cloaks), which can hide objects under
