Abstract
This paper presents the design and simulation of a microwave metamaterial absorber that covers the S, C, X, and Ku frequency bands, which is between 2 and 16 GHz. The design is unique in that it is able to achieve high absorption rates across a wide frequency range, with multiple distinct absorption frequencies. Through simulation, it was discovered that the absorptance is high at 3.286 GHz, 5.873 GHz, 9.968 GHz, 13.348 GHz, 14.076 GHz, and 14.323 GHz, and obtained maximum absorptance rates of 90.04%, 90.706%, 98.711%, 99.73%, 99.976%, and 99.14% at these different frequencies. The results of the proposed MMA design are promising and suggest that it may have applications in areas such as frequency selective surfaces (FSS) and signal-to-noise ratio (SNR) enhancement and refractive index sensing, where precision and a broad spectrum of sensitivity are required.
