The theory is well tested and good.

Authors often write books to inform. They are paid for their efforts.

Skin effect is a fact of agreement among the scientific community. A
proof is readily at hand. Coaxial cable keeps what`s inside in and
what`s outside out.

The best exposition of "skin effect" that I know of is found in chapter
27 of "Radio-Electronic Transmission Fundamentals" by B. Whitfield
Griffith. The 1st edition was published in 1962. It was republished by
Scitech in 2006. Art would enjoy and benefit from all 638 pages.
