These data confirm our previous assessment that three-dimensional cloaking is quite robust for these structures.
An imperfect multi-layered acoustic cloak is proposed for a two-dimensional cloaking zone based on feasible material properties.

These results can be applied as a practical design guide for two-dimensional cloaks using multilayered structures composed of naturally existing materials.
Numerical results from wideband simulations demonstrate that waves passing through a three-dimensional cloak experience considerable delay comparing with the free space propagations, as well as pulse broadening and blue-shift effects.
The researchers said they plan to work toward developing a three-dimensional cloak and further perfecting the cloaking effect.

A parallel dispersive finite-difference time-domain (FDTD) method for the modeling of three-dimensional (3-D) electromagnetic cloaking structures is presented in this paper.
Excellent cloaking effect was verified by simulations.
