Abstract
This thesis proposes a metamaterial absorber that is triple-band polarization insensitive, split-rectangular-C-shaped, rotationally symmetrical, and structured at the C, X, and Ku bands; it is designed for use in whey protein mobility sensing applications. The three-layer MMA design consists of a copper laminated FR-4 substrate layer and a resonating layer made of concentric continuous and split rectangles. At this mixed martial arts event, the C-band, X-band, and Ku band all work together. Surface currents, electric fields, magnetic fields, and the reflection coefficient are just a few of the variables that have been studied to understand the MMA's absorption characteristics. The MMA includes absorbance values of 92% at 4.848 GHz, 7136 GHz at 99%, 97% at 7.584 GHz, 99% at 10.384 GHz, 96% at 17.648 GHz, and 91% at 14.944 GHz. The proposed MMA sensor also provides enhanced sensitivity for detecting moisture levels in the mobility of whey protein polymer by sensing the permittivity fluctuations range (15–25) of the protein. Also, at 4.864 GHz, with a permittivity value of 25, we get a maximum peak absorption of 91%. From 21 to 23, the band shift is as low as 0.016 GHz. Sensing output is provided at 5.1849 GHz, 5.088 GHz, 5.024 GHz, 4.976 GHz, 4.96 GHz, and 4.864 GHz using the MMA sensor arrangement. The average sensitivity of the MMA for different amounts of whey protein permittivity is 0.032099 GHz/(F/m). This MMA has a high absorbance, making it useful for a variety of microwave applications. These include hydrocarbon, permittivity, pressure, and even whey protein polymer mobility detection in some instances sensing.
