## 3 Absorption Characteristics  
Tungsten has a very excellent demonstration to impedance matching in open space, and it does not have any surface plasmon resonance at wavelengths of the optical region. Tungsten is used both for the resonator and back layers in the proposed MMA absorber. This absorber must function as a high-quality potential super absorber since \(Z_{0}\) is slightly less than \(Z(\omega)\). The electromagnetic waves in an incident are handled by a symmetrical design. Metal plane wave occurrences in the rear layer indicate lower transmissions, and front wave resonator and dielectric layer maintenance need further layers. Silicon dioxide (SiO\({}_{2}\)) effectively decreases the wavelength distance because of its common thickness properties. Impedance matching with the open space optical range may also be determined through the characteristics of the basic losses of the front layer as well as the resonance of the dielectric layers. This uniqueness is achieved by implanting the matching wave absorber, which has excellent performance and efficiency. Moreover, these mysteries will reveal excellent absorbance if the equally structured split ring resonator is employed. The wave from the first stage appears in the resonator as a metal screen reflects the wave in a back layer. A metal resonator and a silicon dioxide (SiO\({}_{2}\)) dielectric help to compensate for the front layer, while a metal plane forms the bottom (tungsten). Figure 5 illustrates the reflectance, transmission, and absorbance plot, and Figure 6 shows the absorbance characteristics comparison between TE, TM, and TEM modes. The suggested MMA has a maximum absorbance of 99.99% at 557 nm and an average absorbance of 91.82% from 450 to 650 nm at TM and TE mode.

On the other hand, in TEM mode, there is a wavelength range of 450 to 650 nanometers with an average absorbance of 91.31%. Metamaterial absorbers have a massive decrease in scattered light from ultraviolet to near-infrared. Research in near-infrared using reflectance imaging and transillumination with optical consistency has shown that this area of the spectrum is well suited for observing materials with a high absorbance polarization. Reflectance measurements may benefit greatly from optimizing the contrast of polarization due to the transparency of absorbers constructed from growing metamaterials. This factor also affects transillumination lesions for TE mode electromagnetic waves as opposed to TM mode. In addition, the absorber has a substantially higher level of light scattering than

This research aimed to examine absorbers' attenuation and absorbance of optical-range electromagnetic waves. The attenuation was discovered to rise dramatically with wavelength, which was not always in line with the expected increase in EM wave absorbance. As a result, PCR shifts between TE and TM modes at a lower wavelength. The absorbance property A (\(\omega\)) has been determined with the help of Equation (1) [30]  
\[\text{A }(\omega)=1-\left|\text{S11}(\omega)\right|^{2}-\left|\text{S21}(\omega) \right|^{2}=1-\text{R}-\text{T} \tag{1}\]  
where R and T are the reflectance and transmittance, respectively, S11 is the reflection coefficient, and S21 is the transmission coefficient. \[Z=\sqrt{\frac{\left(1+\text{S11}\right)^{2}-\text{S21}^{2}}{\left(1-\text{S11 }\right)^{2}-\text{S21}^{2}}}=\sqrt{\frac{\frac{\mu}{\epsilon}}{Z_{0}}}=\sqrt{ \frac{\mu_{r}}{\epsilon_{r}}} \tag{2}\]  
where \(\epsilon=\epsilon_{r}\epsilon\) and \(\mu=\mu,\mu_{0}\) are the permittivity and permeability of MMA.
