Achieving broadband perfect absorption has always been a challenge for terahertz bands. Many terahertz broadband perfect absorbers have been proposed, but for most of them, bandwidth with an absorption rate greater than 99% is narrow. In this paper, a simple periodic structure consisting of an open-...
