Abstract
The present invention relates to a man-made composite material. The man-made composite material is divided into a plurality of regions. A plane electromagnetic wave is incident on a first surface and exits in the form of a spherical wave from a second surface of the man-made composite material opposite to the first surface. Reverse extensions of the exiting electromagnetic wave intersect with each other at a virtual focus of the man-made composite material. A line connecting the virtual focus to a point on the top surface of the iregion and a line perpendicular to the man-made composite material form an angle θ therebetween, which uniquely corresponds to a curved surface in the iregion. A set formed by points on the top surface of the iregion that have the same angle θ forms a boundary of the curved surface to which the angle θ uniquely corresponds.
