Absorbers have attracted the attention of plenty of people to implement several applications, including stealth technology that requires flexibility features. Metamaterial absorbers can achieve high absorbance and flexibility features. Polyvinyl chloride is a polymer with flexible features that can be incorporated into metamaterials. This study analyses the tripartite square ring metamaterial absorber fabricated by hand painting. The multiple absorbance peaks are yielded on the tripartite square ring metamaterial absorber. The simulation absorbance peaks are 0.98 at 2.36 GHz, 0.95 at 3.75 GHz, and 0.99 at 4.3 GHz, while the experimental absorbance peaks are 0.89 at 2.7 GHz, 0.68 at 4.0 GHz, and 0.94 at 4.4 GHz. The disparities between simulation and experimental results are delivered due to the inaccuracies in the fabrication method. However, the trend of experimental results agrees with the simulation results. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
