Metamaterials are a new class of artificial materials that emerged at the turn of the century, providing a new method of material construction and revolutionary technology for many technical fields. In the past 2023, research on metamaterials made certain progress in multiple aspects. This article attempts to review some of the main research works on metamaterials from several aspects, including optical metamaterials, thermal metamaterials, mechanics(mechanical) metamaterials, quantum and time-varying metamaterials, and the merging of metamaterials with conventional materials. The future research and development trends in the field are also predicted and anticipated.
