In this study, a metamaterial-based transparent and flexible microwave absorber design was carried out. Transparent PET (polyethylene terephthalate) was used as the dielectric substrate and ITO (indium tin oxide) was used as the conductor for the air and metamaterial structure. The intended absorber provides %90 absorption in the range of 9.6 GHz to 34.8 GHz with a normal incidence angle of approximately 25.2 GHz. Oblique angle performance shows % 80 absorption up to 45 degrees. In addition, the designed absorber works as a polar- ization insensitive absorber as it provides the same absorption performance in both TE and TM polarization under the normal incidance of the electromagnetic wave. The transparent dielectric is only 2.85 mm thickness, making it thinner than comparable ultra-wideband transparent materials. The study was carried out as a simulation in the CST microwave simulator. The results obtained were compared with other reference studies.
