Lateral Shift Makes a Ground-Plane Cloak Detectable

Baile Zhang, Tucker Chan, Bae-Ian Wu
2010 Physical Review Letters  
This cloak without anisotropy will generally lead to a lateral shift of the scattered wave, whose value is comparable to the height of the cloaked object, making the object detectable.  ...  Ray tracing on a concrete model shows that for a bump with a maximum height of 0.2 units to be hidden, the lateral shift of a ray with 45 degree incidence is around 0.15 units.  ...  Although the isotropic ground-plane cloak is able to largely preserve the phase propagation, the energy propagation is subject to a lateral shift which will render the cloak detectable.  ...
