The physical structure of MM determines its properties, not its chemical content. Since it may be used in a variety of applications, such as absorber [3], polarization converter [4], filter [5], imaging [6], antenna [7], invisible clock [8], sensor [9], waveguides [10], etc. The perfect metamaterial absorber was first developed by [PERSON] [11], which started an innovative study area for its unique use in many applications, such as photo-detecting [12], energy harvesting [13], thermal emitter [14], and solar cell [15], etc. Researchers are now pursuing research on the metamaterial perfect absorber design for microwave frequency, visible, infrared, and THz applications and developing low-loss devices by structural optimization [16]. Furthermore, the researcher was attracted to solar energy collecting by the MPA of total visible light, which is 50% of the total visible light [17; 18]. The asymmetrical absorption property can be achieved by using appropriate magnetic and electric resonance engineering. Most researchers have demonstrated various types of metamaterial perfect absorber designs with lower absorption features, such as limited frequency range and lower absorption label [19]. The complete visible optical wavelength range has only been studied in a small number of research concerning the frequency range from 400-790 THz in the visible wavelength range of 380-750 nm. The unique absorption rate at various polarization incident angles required insensitive polarization features for absorber design [20]. Furthermore, It is also essential to have a broad range of incident angle stability to achieve the optimal absorption rate. [PERSON] et al. [21] designed a metamaterial absorber with a maximum absorptivity of 92% by utilizing Au and SiO\({}_{2}\) metal. The visible wavelength range of 370-880 nm has absorption values over 83%. A four-layer optical wavelength absorber based on Cu, Si\({}_{3}\)N\({}_{4}\), and Si materials is constructed for 400-700 nm in work [22], with a peak absorption of 97% and a low absorption of approximately 80%. [PERSON] reported in work [23] that a three-layered metamaterial absorber for a visible range with an absorption bandwidth ranging from 389.34-697.19 nm and absorptivity of 99% was achieved with absorption bandwidths exceeding 91.24%. The absorption level is increased to 70% when the polarization is insensitive, and an incident angle of 60 degrees stability is observed. Work [24] presents a small-size absorber based on Ag and SiO\({}_{2}\) with a reduced absorption level and absorption bandwidth, but the maximum absorptivity value is enhanced to 98% compared to the previous work, where the wavelength range was 300-700 nm. However, the oblique incidence angle stability and polarization insensitivity are absent. The stability of the incidence angle of an Au and Si-based absorber is raised to 65 degrees in the article [25]. However, absorption drops to 80%. In work [26], the author proposed a Ni and Si base absorber for wavelengths ranging from 400 to 700 nm, with more than 90% absorption intensity. After reviewing the previous studies, it is evident that the oblique incidence angle stable MMA and polarization insensitivity with a maximum absorptivity level throughout the entire wavelength range from 380-750 nm is highly required for visible optical MMA applications. This research presents a simple metal-dielectric-metal structured MMA for the optical spectrum from 400 to 750 nm. The PCR is evaluated to ensure that the MMA is perfect. The absorbance characteristics of both the TM and TE modes have been investigated at various polarization angles and oblique incidence angles. The results demonstrate that the absorbance properties of both TM and TE modes are unique. The proposed MMA achieved a maximum absorptivity of 99.99% at the working spectrum with more than 91.82% average absorbance levels. The paper is arranged into different sections for the convenience of presentation. In Section 1, the introduction is given. In Section 2, both the design procedure and the structure are discussed.
