Abstract
The design equations of a neutral coated inhomogeneity with confocal elliptic interfaces are derived, when the elastic matrix is subjected to a longitudinal shear. The neutrality of such an inhomogeneity is achieved by inserting an appropriate coating between inhomogeneity and matrix provided that the longitudinal shear applied to the matrix is parallel to one of the elliptical semi-axes. The above general results are verified numerically by designing specific neutral inhomogeneities using finite elements.
