Abstract :
A definition of the Rayleigh region is presented in terms of the radius of convergence of the Rayleigh or low-frequency expansion which is both mathematically precise and consistent with current usage in radar scattering work. General methods for obtaining successive terms in low-frequency expansions are outlined and those special shapes for which calculations have actually been carried out are enumerated.
