Design Arbitrary Shaped 2D Acoustic Cloak without Singularity (2009)
Hu, Jin, Zhou, Xiaoming, Hu, Gengkai
A method is proposed to design arbitrary shaped two dimensional (2D) isotropic-inertia acoustic cloaks without singularity. The method is based on the deformation view of the transformation method,...
Nonsingular two dimensional cloak of arbitrary shape (2009)
Hu, Jin, Zhou, Xiaoming, Hu, Gengkai
We propose a general method to circumvent the singularity of arbitrary 2D cloaks, which arises from infinitely large values of material parameters at inner boundaries. The presented method is based...
Calculation of material properties for arbitrary shape transformation media (2008)
Hu, Jin, Zhou, Xiaoming, Hu, Gengkai
We propose a general method to evaluate the material parameters for arbitrary shape transformation media. By solving the original coordinates in the transformed region via Laplace's equations, we can...
Design Method for Electromagnetic Cloak with Arbitrary Shapes Based on Laplace's Equation (2008)
Hu, Jin, Zhou, Xiaoming, Hu, Gengkai
In transformation optics, the space transformation is viewed as the deformation of a material. The permittivity and permeability tensors in the transformed space are found to correlate with the...
