Metamaterials, which are called as left-handed materials, exhibit electromagnetic properties that do not exist in nature, such as negative refractive index and reverse Doppler effect, at the frequency range for which they are designed. These unique properties of metamaterials have made them indispensable in a wide variety of applications such as sensor applications, signal absorption, antenna, and energy harvesting. In this study, the design and analysis of a metamaterial (MTM) perfect absorber at 5 GHz frequency band were performed to investigate the usability of the proposed structure in energy harvesting applications. A negative refractive index of -0.15 was obtained at 5GHz. The variation of absorption, transmission, and reflection of the proposed MTM structure exhibited that a maximum absorbance was monitored at 5 GHz as 0.9949. According to the harvesting application study, the proposed structure has a maximum absorption of 88.3% at 4.98 GHz which is close to resonant frequency in 8000 Ω resistor value. The results of the study revealed that the proposed MTM structure has potentials to be used in energy harvesting applications.
