Comments on "Potentials Produced by Arbitrary Current Sources in an Infinite-and Finite-Length Circular Conducting Cylinder"

Recently in this TRANSACTIONS, a paper was published1, dealing with the electric potential problem in a circular conducting cylinder. The authors criticize the approach to the same problem as proposed by Okada in 1956. Obviously, an important motive for preparing the paper was the existence of contradictory results from different solution methods found in literature. We want to rehabilitate Okada´s paper. We will point to the small error in Okada´s paper. Correction of this error removes the confusing difference with other methods.
