I have been accused in the post shown earlier in this thread, without either any reason or evidence, of providing “B.S.” in my technical replies and comments regarding antennas and related subjects.
Thus I wanted to offer the post from another recent thread which coincidentally addresses related RF discussion.
The true source of “B.S.” becomes immediately apparent here and I clearly have no problem proving my counter-claim:

That is why people consider OTA “voodoo art” even though it does follow the scientific rules of RF signal propogation and Maxwell’s theorems\equations.
What in the world are you talking about?
Maxwell’s Theorem is utterly and totally unrelated to RF. There is only 1 such theorem, not several, and it has nothing to do with RF whatsoever.

Maxwell’s theorem
In probability theory, Maxwell’s theorem, named in honor of James Clerk Maxwell, states that if the probability distribution of a vector-valued random variable X = ( X1, …, Xn )T is the same as the distribution of GX for every n×n orthogonal matrix G and the components are independent, then the components X1, …, Xn are normally distributed with expected value 0, all have the same variance, and all are independent. This theorem is one of many characterizations of the normal distribution. Since…
And as regards Maxwell’s Equations:
Maxwell’s Equations apply to RF propogation but only in a very abstract sense that they apply to all electrodynamic fields such as optics and acoustics. The RF engineer does not use them as a practical tool in OTA or propagation work. They are a useful and important analytical / midelling tool for generalized descriptions of how charges, currents, and fields relate.

Maxwell’s equations
Maxwell’s equations are a set of partial differential equations that, together with the Lorentz force law, form the foundation of classical electrodynamics, classical optics, and electric circuits. These fields in turn underlie modern electrical and communications technologies. Maxwell’s equations describe how electric and magnetic fields are generated and altered by each other and by charges and currents. They are named after the physicist and mathematician James Clerk Maxwell, who published an…
Sorry Craig. I don’t appreciate being falsely accused with no evidence to back it up.
