In later 1980s, microwave sintering technique was introduced into the materials science area [1-2].
Therefore, the homogeneous of the microscopic structure of materials are improved [3].
(2) Materials Properties The model consists of two kinds of materials: air and copper.

Although the propagation of mechanical waves in periodic composite materials is an old topic in condensed matter physics and in acoustics [7], the search for band gaps in PCs increased recently [3–5,8–11].
Results and Discussion Epoxy and Al2O3 are polycrystalline materials, and may be treated as isotropic on macroscopic scale.
These defects could modify the elastic wave propagation in composite materials altering the band structure of them.

It is suitable to describe the nonlinear viscoelastic behavior of materials.
Thus, based on the previous studies, a new damage parameter is introduced into the Burgers rheological model in the unidimensional form: (2) where is the uniaxial strain, A is damage value, and B, C are determined by the materials. ε0 is the threshold of accelerated creep.
