This paper presents a model, design, and implementation of a metasurface electromagnetic (EM) wave absorber for operation in the frequency range of the X-band. The model of the metasurface was constructed withasplit ring resonator (SSR) and a stripline and it was designed with a single unit cell, whereby the results were approached with transmission linetheoryfor patch impedance extraction.Implementation of a metasurface EM wave absorber was deployed on an FR4 Epoxy dielectric substrate with dimensionsof 80-unit cells ×80-unit cells and characterized with two horn antennas,which were connected to a signal generator as thetransmitter and a spectrum analyzer as thereceiver. In front of the horn antennas a device under test (DUT) was installed, i.e., a metasurface EM wave absorber and a metal plate with similar dimensions. Themetal plate was expected to perform full reflection atthe same distance and antenna orientation. Thesame condition was used as a normalization factor to optimizethe absorption of the metasurface EM wave absorber. The characterization results showedthat the minimum normalized absorption of the SRR and stripline at the designated measurement distances was 0.99, 0.99, 0.99, and 0.97, at frequenciesof 8.85 GHz, 9.08 GHz, 9.15 GHz, and 9.10 GHz, respectively, and a 0°antenna orientation
