Abstract

An innovative metamaterial (MTM)-based microwave absorber is proposed to feature a unique combination of rectangular and hexagonal resonators, tailored for multi-band absorption across the S, C, and X frequency bands. Built on a Rogers RT 3010 substrate, the proposed Metamaterial Absorber (MMA) demonstrates enhanced absorption efficiency, polarization independence, and angular stability. The absorber achieves multiple resonances at 3.36 GHz, 3.64 GHz, 5.06 GHz, and 6.36 GHz, with absorption values 90 %, 99.5 %, 99.7 % and 99.8 % validated through simulation analysis. The design evolution, progressing through resonator stages A, B, C, and D, highlights the impact of structural complexity on performance improvements. Experimental results align closely with simulations, showcasing minimal deviations due to fabrication imperfections. With its compact dimensions and high effective medium ratio (EMR), this MMA surpasses existing designs in multi-band functionality and efficiency, making it suitable for applications such as electromagnetic interference (EMI) shielding, radar systems, and wireless communication.
