There is some worrying plagiarism on the www at
Sections of it are copied from my oct80 book "Electromagnetic Theory vol 2" without proper crediting, although my name is mentioned once. They are mixed up with other stuff not by me.
The sections which are mine are more or less;
"The nature of space"; "General description of energy transfer", and "The fallacy of displacement current". This last is in my Wireless World dec78 article.
Please would the author of that web address clarify which parts are mine and which are not. There are some important matters there, which are not mentioned anywhere else except in my little known oct80 book. However, they have been mixed up with other material.

This is an example of the plagiarism;Continuing our discussion of space and the values of c, Zo, µ, we take as given that real space sustains non-zero finite impedance and velocity as follows: ……………. where: µ and are characteristics of a unit volume As yet we have not arrived at volume, which implies real space. At this point in our discussion we have merely described c and Zo . Therefore, we can only define µ and in terms of them. Algebraically it can be shown that: ………………. Although we have said that the fundamental characteristics of space are c and Zo , perhaps it is better to say that they are t and Zo , where t is the time delay through a finite segment of space replacing c, the velocity through that segment. It is profitable to move away from the idea of constant velocity c travelling through space which leads one to conceptualization of a segment of space which traversed in 1 nanosecond (nsec) is 1 foot long. If one starts with a conceptual frame in which space is in terms of t, a segment of space can easily be though of as 1 nsec wide, and the energy entering it appears leaving it 1 nsec later. Subsidiary concepts of length and velocity can then be deduced as needed. We could alternately say that space was (a) 1 foot wide with a propagation velocity of 1 foot/nsec, or (b) 2 feet wide with a velocity of 2 feet/nsec. Fundamental to the proposed world view is the reality that no experiment could help us decide between (a) and (b). The essence of space is time, not distance, and only one propagation velocity () is possible through a segment of space. Thus, time through a segment is intimately related to the length of the segment. Propagation which is not at the speed of light cannot exist according to this world view. ……………………………. Now see my oct80 book "Electromagnetic Theory vol 2, pub. C.A.M. Publishing, England, which was plagiarised above. Space must have finite impedance and sustain finite velocity. ………….. u, E are of course the characteristics of unit volume. But we have not yet arrived at volume, which implies distance (space) at this point in the argument. All we have so far is c and Z. Therefore, u and E must be defined in terms of them. It turns out (by algebra) that ………….. Although we have said that the fundamental characteristics of space are c and Z, perhaps we should say instead that they are Z and t, t being the time delay through a segment of space AB and replacing c, the velocity through that segment. We should try to get away from the idea of constant velocity through space c, which leads to the idea that a segment of space which is traversed in 1 nsec is 1 foot long.
