High Directive Antenna with Virtual Aperture

In this article, we propose a spherical shell-core structure which is able to achieve arbitrarily large directivity. The structure is obtained from coordinate transformation. A small antenna can be projected to free space with a large dimension, which subsequently leads to a large directivity.
