Figure 24

Real and imaginary parts of the displacement component in -axis, , at the interface between the isotropic matrix and the outermost layer for (a) the single triple-layered elliptical (90°) inclusion (Inc. #4), (b) the seven triple-layered elliptical (90°) inclusions (Inc. #4) with , and (c) the seven triple-layered elliptical (90°) inclusions (Inc. #4) with . The frequencies used are = 3.14, 5.03, and 7.85, where is wavenumber in the unbounded isotropic matrix and is the major radius of the elliptical inclusion.
