In reference number [3, Vander Vorst et al](page 41) (for the general formula of skin depth) the equation is wrong compared to the right equation in reference number [4, Jordan, Edward Conrad] (and in the text). Maybe remove this reference. Formula from [4] and in the article have been verified with the typical copper skin depth of 9.3 mm at 50 Hz. Formula from Reference [3] delivers 1 mm.
