rectenna improbable. Obviously, the torus crown diameter is a direct function of its packaging efficiency. But. while significantly larger efficiencies for the torus would be in itself risky, the fact that the membrane packaging would have to grow quadratically sets a clear limit in this direction; i.e. (after Bemasconi. Kose and Rits. 1989): The required quality of the rectenna surface is another issue that limits the growth of the rectenna. It has been assumed that the rectenna must be kept within 1 mm of a reference plane against the effect of the acceleration. Now. it has been shown - using linear theory - in ID-RVW/270-991/FPP that in order to avoid buckling of the torus ring under the tension load required to maintain the membrane s flatness:
