Abstract

In this paper, we propose a new GL EM 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. Our GL EM cloak is created by GL EM cloak modeling and inversion with searching in a class of the rational function of (h), h = r − R1. The GL cloaks in this paper have finite speed and have no exceed light speed physical difficulty. The GL EM cloaks can be practicable by using conventional optical materials Radial GL EM inviavible cloak modeling, inversion and electromagnetic integral equation for cloak are proposed in this paper. The 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. At time steps 118dt, in the GL cloak, the wave front is curved as a crescent like and propagates slower than the light in free space. At the time step 120dt, 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.
