Figure 3

(a) Is a plot of the anomalous reflection force (dashed green), specular reflection force (dashed red), incident electromagnetic force (solid black), and net force (bold green) for the lateral components of the solar sail. (b) Is the same, but for the normal components. (c) Is the ratio of the net forces from solely the specular case (bold red) and from the anomalous cases of varying phase gradient (the rest of the bold colors). All plots have the parameters, ηanom = 0.75. (a and b) have ζ = 0.71k0.
