The working phenomenon of the non-contact illusion device that distantly modifies the array of sources into a desired manner. (a) The emission of the linear array of antennas is distantly manipulated in (b), so the observer outside the non-contact device has the impression that the radiation comes from different geometrical structure of antennas’ array, which is optically equivalent to (c). (d) Schematic diagram: in the first step, the brown colored array sources made of \(N=22\) elements with the current density of each is \(1/2\) are linearly transformed into a linear array made of \(N=11\) elements with the current density of each is \(1\), which can be seen in red colored. The second step is based on Fig. 1(d).
