The series need not converge but provide an asymptotic representation of the field, which is especially useful at small wavelengths. The full asymptotic representations are built from knowledge of the pulse solution of Maxwell's equations which is established by a source, with the same geometrical distribution as the source of the steady state field. The author shows that the discontinuity in E and H which exists on any wavefront created by the sudden introduction of a charge or by reflection and refraction is precisely the value of E and H given by geometrical optics. The author also shows that the discontinuities in the E and H of the pulse solution at any fixed point in space at which v and o are continuous and at which there are no charges are discontinuities on wavefronts. Hence these discontinuities, which are given by geometrical optics, furnish the amplitude of the first term of the asymptotic expansion of the steady state field.
