Determining the full transformation relations in the transformation method
Jin Hu, Xiang-Yang Lu
Transformation method provides an efficient way to control wave propagation by materials. However, the degree to which this transformation concept can be applied to other physical…
Transformation Ray Method: Controlling High Frequency Elastic Waves
Zheng Chang, Jin Hu, Xiaoning Liu +1
A transformation method based on elastic ray theory is proposed to control high frequency elastic waves. We show that ray path can be controlled in an exact manner, however energy…
Controlling elastic wave with isotropic transformation materials
Zheng Chang, Jin Hu, Gengkai Hu +2
There are great demands to design functional devices with isotropic materials, however the transformation method usually leads to anisotropic material parameters difficult to be re…
An approximate method for controlling solid elastic waves by transformation media
Jin Hu, Zheng Chang, Gengkai Hu
By idealizing a general mapping as a series of local affine ones, we derive approximately transformed material parameters necessary to control solid elastic waves within classical…
Design method for quasi-isotropic transformation materials based on inverse Laplace's equation with sliding boundaries
Zheng Chang, Jin Hu, Xiaoming Zhou +1
The deformation method of transformation optics has been demonstrated to be a useful tool, especially in designing arbitrary and nonsingular transformation materials. Recently, the…
Design Arbitrary Shaped 2D Acoustic Cloak without Singularity
Jin Hu, Xiaoming Zhou, Gengkai Hu
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 trans…
