| Abstract: | Nowadays, radar and satellite communication are crucial technologies that utilize electromagnetic waves and are essential for numerous applications. In this work, we numerically designed a novel metamaterial broadband absorber operating in the frequency range of 10–18 GHz, achieving over 90% absorptivity across a broad bandwidth from 12.55 GHz to 15.11 GHz. Computer Simulation Technology (CST) was employed to simulate and investigate the proposed design. We conducted parametric studies, analyzed the waveguide port on different axes, and provided a step-by-step design layout of the proposed metamaterial unit cell, along with field distributions. To validate the simulation results, we successfully fabricated and tested the metamaterial absorber. The experimental results demonstrate an absorption rate exceeding 90% from 12.52 GHz to 14.31 GHz, aligning well with the numerical simulations. The proposed design was also utilized for the detection of cervical cancer, exhibiting sensitivity of approximately 3.16 GHz/RIU. The novelties of this study include its simple design, ease of fabrication, low cost, compact size, and broadband performance. Furthermore, the proposed design holds significant promise for real-world applications due to its reconfigurability. Our innovative metamaterial absorber has potential applications in television broadcasting, detection systems, and biomedical sensing. [ABSTRACT FROM AUTHOR] |
