From: Non-contact method to freely control the radiation patterns of antenna with multi-folded transformation optics

Figure 1The alternative text for this image may have been generated using AI.

The working phenomenon of the non-contact illusion device that distantly delocalizes the emission of antenna into a desired manner. (a) The emission of the radiating antenna in free space is in forward direction, which is distantly manipulated by non-contact device (b). Observer outside the non-contact device has the impression that the radiation comes from another emitting antenna’s direction, which is optically equivalent to (c). (d) The schematic diagram of proposed non-contact device. In virtual space: current source, PEC and the referenced EM medium exist. After applying the transformation only referenced EM medium is compressed and shifted towards the compressed region I. Region I is further coated with the folding region II. In all cases, the linear source and PEC remains same.
