 This study examined quad-band metamaterial perfect absorbers, MPAs, which are designed to reduce electromagnetic interference, EMI. The MPA consisted of two X-shaped rings, a dielectric substrate, a copper ground layer, and a sensing layer. The MPA achieved high absorption rates of 99.9%, 99.9%, 99.9%, and 99.8% at four different frequencies, 4.87 GHz, 7.49 GHz, 11.78 GHz, and 13.09 GHz for both the transverse electric, T, and transverse magnetic, TM, modes. Additionally, the MPA provided a shielding effectiveness of over 45 dB across all bands in both T and TM modes. The MPA was also tested using an analogous circuit, which confirmed its performance.
