Abstract

The realization of object invisibility in the microwave region is of great tactical importance. Herein, we report on designing and simulating a carpet-based cloak composed of a thin dielectric metasurface. Initially, simulations were performed to fix the texture and design of the carpet. For this purpose, a single-frequency TE mode was chosen, and simulations were conducted to investigate reflection at a launched electric power at a varying angle. The dielectric surface has been architected with one order of magnitude mismatch in the design texture. The study revealed that the texture could conceal the object effectively to an extent, thereby not changing the signature of the reflecting field. The power loss analysis was carried out for different launch power on the carpet. Linear, circular, and elliptical excitation modes of plane waves have been studied and observed. Electric field and far-field analysis have been discussed and correlated for the developed carpet geometry. Details have been presented.
