Abstract

A metasurface absorber based on the slow-wave effect has the advantages of long interaction time and high absorption. A slow-wave metasurface absorber is constructed using the periodic arrangement of the Jerusalem cross, which achieves a reflectivity of −15.0 dB at 5.0 GHz. Furthermore, dual-frequency absorption is realized by the coupling of two unit cells with different sizes. The calculated delay time of metasurfaces further confirms the underlying absorption. The design of metasurfaces through the slow-wave effect provides new ideas to the field of absorbing metasurfaces and creates broad application prospects.
