| Abstract: | We present a series of invisibility concentrators with simplified material parameters beyond transformation optics. One of them can achieve the perfect invisible effect at frequencies of Fabry–Pérot resonances, while others have very small scattering. The required materials are feasible in practice. Analytical calculations and numerical simulations confirm the functionalities of these devices. |
| Keywords: | perfect-invisibility concentrator simplified material parameters Fabry–Pérot resonances scattering cross section |
