Abstract: Terahertz (THz) electromagnetic waves share a few of the characteristics of optical and gigahertz waves, which makes them suitable for a number of interesting and new applications in imaging, spectroscopy, characterization, sensing and monitoring. Recently, there has been a huge interest in developing THz devices that can achieve this potential. One of these devices is a metamaterial THz perfect absorber, which was first proposed in 2008 and is believed to form the basis for future room temperature THz detectors. Since then, a large amount of research has been focused on developing such THz absorbers with various properties, including dual band, multiband, wide band and polarization insensitivity. In this article, we present a brief review of the current state-of-the-art of THz metamaterial absorbers and discuss in more detail two specific THz absorber structures.
