A very brief look at Balanis "Antenna Theory" has the passing comment that
proximity effect can lead to greater loss than skin effect (on a discussion on
small loops). He references G. Smith, The proximity effect in systems of
parallel conductors", J Applied Physics, Vol 43, no 5, May 1972 pp 2196-2203.

Perhaps someone who has access to a university library could take a look
and see what the article reports.

Surprisingly that particular graph is not in my second edition. Is there another book? Mine is simply entitled Radio Engineering.

I also possess Radio Engineering by Terman and it is fine as a textbook. But as a reference manual Radio Engineers Handbook is much more useful, in fact it is still a superb piece of work. Look out for a copy!
I attach the title page.
