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.

Introduction. The quest for optically transparent microwave devices has increased over the last years. This growing research interest is driven by the opportunity to combine photonic and microwave technologies, thus creating new applications 1, 2.In this framework, one important aspect is related to the ability to manipulate and control reflection, transmission and absorption of microwave.

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.
