Conventional wisdom to realize transparency demands minimizing disordered light scattering. Nevertheless, achieving a matte appearance necessitates disordered light scattering, as demonstrated in Fig. 1A.Therefore, for a long time, transparency and matte appearances have been considered two conflicting optical properties that cannot coexist in the same material.

1. Selecting a material with a low dielectric constant (Relative permittivity) will be the most transparent. Specifically, you need to select one that is low for the use temperature and for the use frequency of 2.5GHz. This level of information is not easy to come by, but there are some online tables that will give ballpark dielectric constants.

Table 1 presents the optical and microwave absorption perfor-mances of recently reported representative transparent micro-wave absorbers. The MGSS prepared in this study showed an excellent absorption bandwidth (A ≥ 50%) with a peak absorp-tion eficiency of near unity, indicating its slow downward trend. Figure 8.
