The ultrasound, as a mechanical wave, can directly reflect materials’ inner structure and mechanics performance [7].
The variable D is used to evaluate the decline of materials’ property after impact and bending
Hence, the materials’ carrying capacity also reduces.

Introduction Zinc Oxide is a kind of important functional material of II-VI with hexagonal wurzite structure, and direct wide band gap of 3.37eV.
ZnO has many advantages, such as higher exciton binding energy and lower growth temperature, and good chemical stability, which make it more suitable blue and ultraviolet emission material at room or higher temperature, which in turn become important candidate material.
The target materials were 99.99%Zn, and the oxygen and argon are 99.99% purity.

Introduction In recent years, transformation optics has aroused intensive research interests because it provides a flexible approach to controlling electromagnetic waves by artificial materials, metamaterials [1, 2].
This technique adds a significant amount of flexibility to the design of complex materials and has been successfully applied to design parallel beam splitter and beam deflector [19].
A transverse electric (TE) Gaussian plane wave (with electric field normal to the x-y-plane) is incident on the slab filled with transformation materials from the left with (is the wavelength in free space).
