Abstract : The effort on the problem of scattering by complicated shapes is part of a long range program, the ultimate goal of which is the theoretical determination of the electromagnetic (and acoustic) scattering properties of an arbitrarily shaped target to any desired degree of accuracy. Though this goal may never be fully attained, considerable activity, both in the Radiation Laboratory and in the field in general, has produced a variety of approximate techniques as well as exact solutions, thus considerably enlarging the class of shapes whose scattering properties can be said to be known. One concern has been refining techniques applicable for low frequencies (wavelength large with respect to scatterer) to extend their range of validity. This effort has met with considerable success.
