Abstract

In this paper, square-shaped water metamaterial is reported, which can be used as a perfect absorber for ultra-broadband absorption in the microwave frequency range. Computer Simulation Technology (CST) software was used to investigate the results numerically, while a 3D printing technology was used to fabricate the proposed design. The simulated and experimental results showed that the proposed structure achieved absorption of more than 90% in the frequency range from 10.4 to 30 GHz. Moreover, the proposed metamaterial-based system was able to show polarization insensitivity and to maintain a high absorption response in the temperature range from 0 to 100 degrees C, which reaveled a good thermal stability. The absorption mechanism was elaborated taking into consideration the power loss, electric and magnetic field distributions at three resonant frequencies of 12.1, 17.5 and 24.97 GHz. The performance of the proposed system was seen to outperform that of the reported works in literature. It is believed that the metamaterial structure can be a good candidate for the application of energy harvesting and stealth technology due to the high absorption, thermal stability, low cost and easy fabrication of the proposed design.
