I work with a number of middle aged ones (well, 30 - 50 anyway) who also know next to nothing about inductors, wire antennas, or even radio communications. A couple of them are world experts in the fields of radar and radar countermeasures too! Also, when I mentioned radiative and reactive fields to a so-called antenna expert here, he looked blank, then had to stop and think. Appears his 'expertise' really just relates to running antenna contracts with several commercial concerns. The standards of electronics taught in universities, especially as regards basic theory (rather than easier to teach software modelling), is very bad, and getting still worse - some graduates can't even apply ohms law to a practical situation.
