摘　　要：Starting from optical nihility media (ONM),we design several intriguing devices with transformation optics method in two dimensions,such as a wave splitter,a concave lens,a field rotator,a concentrator,and an invisibility cloak.Though the extreme anisotropic property of ONM hinders the fabrication of these devices.We demonstrate that those devices could be effectively realized by simplified materials with Fabry-Pérot resonances (FPs) at discrete frequencies.Moreover,we propose a reduced version of simplified materials with FPs to construct a concentrator and a rotator,which is feasible in experimental fabrications.The simulations of total scattering cross-sections confirm their functionalities.
