The work aims to explore the application background of metamaterial cloaking, review its state-of-the-art progress, and prospect its development trend. Based on the basic principles of operation, the realization methods of several popular metamaterial cloaking methods were discussed, including transformation-based optics, plasmonic and mantle cloaking, cloaking based on microwave network, and phase-tailoring metasurface cloaking. The results demonstrated that the development of metamaterial provided brand-new idea for design of cloaks and promoted the development of miniaturization, integration, digitization, and intelligence of the cloaks. At last, the research progress of metamaterial clocking is overviewed and a brief perspective on its development trend is given.
