Abstract: Metal-dielectric-metal metamaterial structures have enabled near-unity absorption with deep sub-wavelength thickness. The high absorption and low mass volume, as well as the structure simplicity, compactness and design flexibility, are important for many potential applications. They have attracted great worldwide interest in the whole electromagnetic spectrum range, and may have special significance in the terahertz regime. This paper provides a brief review on the development of terahertz metamaterial perfect absorbers, particularly focusing on the design principle, thickness reduction, bandwidth broadening, and theoretical modelling.
