An improved empirical formula for the electric field near the surface of field emitters

A combination of numerical and analytical techniques is used to develop an improved empirical formula for the electric field near the surface of field emitters. The new relationship is shown to account accurately for the shank variation and the dependence of the field upon polar angle. Also discussed is the suitability of empirical formulas for ion trajectory calculations.
