N2 - Controlling the absorptivity and transmissivity at different frequency bands has great importance in microwave and optical camouflage for both civil and military applications. In this paper, the ultra-broadband water-based metasurface absorber is designed with all-dielectric design, which is fabricated with optically transparent materials polymethyl methacrylate (PMMA) and structured water. The high absorption over 90 % of this ground-free structure is achieved from 12.8 to 33.8 GHz with a relative bandwidth of 90 %. This easy-to-fabricate design can be obtained by stacking the PMMA substrate after laser cutting method. The design offers a simpler and available promising way to achieve optically transparent and ultra-broadband microwave absorption for metamaterial absorbers.
