A New Practicable GLLH EM Invisible Cloak without Exceeding Light Speed Wave
In this paper,we propose a new GLLH EM invisible cloak class without exceeding light speed.The GLLH cloak material in this paper is different from our paper ArXiv 1050.3999.The refractive index of the GLLH cloak material,n(r),is large than one or equal to one.Our GLLH EM cloak is created by GL EM Cloak modeling and inversion with searching in a class of the function of am,n logn(bm,n=h)hm,h = r-R1.The GLLH cloaks in this paper have finite speed and have no exceed light speed physical difficulty.The GLLH EM Cloaks can be practicable by using conventional optical materials Radial GLLH EM invisible cloak modeling,inversion and electromagnetic integral equation for cloak are proposed in our recent ArXiv paper.The properties of our GLLH EM cloak are presented in this paper.The novel EM wave propagation and front branching in the GLLH Cloak by GL EM modeling are presented in this paper.The EM wave front propagation in GLLH Cloak is behind of the front in free space.At time steps 118 dt,in the GLLH Cloak,the wave front is curved as a crescent like and propagates slower than the light in free space.At the time step 119 dt,the EM wave inside of the GL EM cloak propagates slower than light speed,moreover,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.All copyright and patent of the GLLH EM Cloaks and GL modeling and inversion methods are reserved by authors in GL Geophysical Laboratory.
