The teaching of well-founded, practice-oriented EM field measurement technology on a scientific basis is the central concern of Dr.-Ing. Martin H. Virnich's book. In an easily understandable form and without "higher" mathematics, the author clearly presents the fundamentals of field theory in a depth necessary for practice. Core topics of his book are the following aspects: Physics of EM fields, Measurement of vector fields, Alternating electric fields (low frequency and DC fields), Alternating magnetic fields (low frequency and DC fields), Electromagnetic waves (high frequency), "Dirty Power", as well as The alteration of the natural EMF spectrum and its consequences. New to this 2nd edition is a detailed section on 5G NR, which deals with the current mobile communications standard and its many manifestations. In doing so, it dispels a number of myths surrounding 5G.
