Utilizing a multiband metamaterial protection has diverse requests across various fields on account of its singular electromagnetic properties. Some key applications involve: Radar Cross-Section (RCS) Reduction, Stealth Technology, Electromagnetic Compatibility (EMC), Antenna Design, Medical Imaging, Energy Harvesting, Aerospace Engineering, Material Testing. This chapter presents a simple simulation of a multi-band metamaterial protection intended for cook frequencies. The projected unit container is composed of two policeman rings placed at different sweeps on an FR4 substrate with a density of 2.5 mm, enabling the production of multiple incorporation bands. While the conventional uneven ring structure frequently responds to electromagnetic (EM) wave polarization, the creative Penta-Perfect Metamaterial Absorber (PPMMA) structure introduced in this place study showcases the capacity to efficiently absorb EM waves across a broad range of occurrence angles. According to CST simulation effects, the PPMMA structure exhibits five different absorption bands, realizing complete metamaterial absorption for usually incident electromagnetic waves at frequencies of 12.25 GHz (absorbance of 91.3%), 12.9 GHz (absorbance of 99.3%), 16.15 GHz (absorbance of 93.7%), 16.78 GHz (absorbance of 98.2%), and 18.44 GHz (absorbance of 97.4%).
