1. Effect of slenderness on optimal shapes.
Effect of slenderness on optimal shapes. δ*-Optimal structures (from Table 1) with twofold reflection symmetry (top) and skew symmetry (bottom). Propellers’ aspect ratio varies from left to right from 1:3 to 1:7 (top) and from 1:4 to 1:8 (bottom). The (red) arrow in the bottom panel corresponds to the direction of the magnetic moment m maximizing δ*.
