WebThe conceptual definition of RCS includes the fact that not all of the radiated energy falls on the target. A target‘s RCS is most easily visualized as the product of three factors: projected cross section, reflectivity, directivity. Reflectivity is defined by the percent of intercepted (scattered) power reradiated by the target. Directivity WebIn this paper, a broadband metasurface absorber using phase change material covering the visible region (500 THz to 740 THz) is numerically investigated. The top metallic layer comprises an array of Jerusalem shaped structures periodic in the x-y direction placed above the Ge 2 Sb 2 Te 5 (GST) layer. The GST layer is followed by a thick metallic layer …
