A precise method of calculation of skin effect in isolated tubes

A precise method of calculation is describ d for determining the skin effect in isolated tubular conductors. This may be used where more accurate results are desired than are given by the curves and approximate methods of calculation previously published by the writer. The present calculation requires the use of certain numerical values of Bessel functions, a table for which is given. Asymptotic series for calculating them are given, which are complete with their general terms. An example is worked out, and the result checked up with the published curves.
