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…

Negative effective mass below a cut-off frequency
Shanshan Yao, Xiaoming Zhou, Gengkai Hu
Negative mass phenomena occurring below a cut-off frequency is examined by both theoretical and experimental methods. The paper begins with the investigation on a mass-spring struc…
