Impedance boundary condition on a PEC backed uniaxially anisotropic sheet of arbitrary shape

Impedance boundary condition is investigated on a PEC backed uniaxially anisotropic sheet of arbitrary shape based on the distributional tools on an arbitrary regular surface. The investigation provides a generalization of the distributional procedure introduced by İdemen in 1993 for the case when the material sheet is of arbitrary shape and backed by a perfect electrical conductor. The availability of an impedance boundary condition is scrutinized for 8 different types of materials of practical interest.
