This paper presents the design and construction of a carpet-based anti-radar coating for frequencies from 8 to 10 GHz. The basic idea of the proposed method is to use a coating to guide microwaves around an object so that what is inside the coating becomes invisible. The proposed method uses metamaterial structures with heterogeneous properties to create coatings that provide complete bounding and prevent loss. Using the theory of light transformation and Zhukovsky mapping for the physical dimensions of the bulge to be invisible, the profile of the refractive index distribution with respect to the radiation of waves is determined. The simulation results of the refractive index profile have shown that it is possible to create an ideal invisible coating for each bulge by using the proposed unit cells and a layer-by layer-structure. Finally, after photolithography of the design on the 5880 fibers using a network analyzer and a pair of corrugated wave antennas, the accuracy of the proposed coating performance is confirmed.
