Abstract :
The inner structure of a heterogeneous two-dimensional object interacting with an external electromagnetic field is completely accounted for by a pair of surface operators that yield the field components tangent to the outer surface exclusively in terms of a single unknown current density distributed on that same surface. Such an equivalent surface representation is invariant under rotation and translation, and is independent of external material and illumination
