Fig, 3.8. (a) Transversal electric field distribution in the radial direction for good approximation
case. Solid line: exact form; dash line: Gaussian approximation, (b) Transversal electric field
distribution in the radial direction for bad approximation case. Solid line: exact form; dash line:
Gaussian approximation.
