A New GL Anisotropic and Isotropic Invisible Cloak without Exceeding Light Speed Violation
In this paper,we propose a new GL EM anisotropic and isotropic invisible cloak class without exceeding light speed.The GL cloak material in this paper is different from our paper ArXiv 1050.3999.The radial dielectric and permeanbility of GL EM cloak in this paper are large than one.The refractive index of the GL cloak material,n(r),is large than one or equal to one.A unconventional GL radial EM cloak modeling and inversion are proposed here.By searching in a distinctive class of the rational function of(h); h=r-R1,the GL EM cloak modeling and inversion create GL EM invisible cloak class without exceeding light speed.The GL EM cloaks can be practicable by using conventional optical materials.he properties of our GL EM cloak and their proofs are presented in this paper.The novel EM wave propagation and front branching in the GL cloak by GL EM modeling are presented in this paper.The EM wave front propagation in GL cloak is behind of the front in free space.In the GL cloak,the wave front is curved as a crescent like and propagates slower than the light in free space.Its two crescent front peaks intersect at a front branching point.At the front branching point,the front is split to two fronts.The novel front branching and crescent like wave propagation are displayed in figures in this paper.A more exciting breakthrough progress is that we discovered GL isotropic invisible cloak without exceeding light speed.The isotropic relative dielectric and permeability parameter are proposed as(4)-(5)and(7)in our full paper.All copyright and patent of the GL EM cloaks and GL modeling and inversion methods are reserved by authors in GL Geophysical Laboratory.
