In the History you find how many people analysed the issue:
longitudinal vs. transversal. In 1905 all stop.
But after 1905 peole build antennas. And they do not worry what the
radiation is like.
Sunner or later the issue appears again.
S*

only when time travelers bring back scientists from the 1800's... or
people like you try to reinvent the discarded theories of old.


Some theories are taught some not. But people after 25 can use what they
want. It seems to me that engineering people do not use the EM theory.

Theories that aren't taught have probably been dropped for a good reason.
usually because they are wrong or don't do anything useful. I don't know
about other engineers but i use EM theory, all my antennas were designed
using it, and i test it regularly with my own equipment... it has never
failed me.


You do not use the EM theory. In EM no electrons. You use electrons:
"Electronics is a branch of science and technology that deals with the flow
of electrons through nonmetallic conductors, mainly semiconductors such as
silicon. It is distinct from electrical science and technology, which deal
with the flow of electrons and other charge carriers through metal
conductors such as copper. This distinction started around 1906 with the
invention by Lee De Forest of the triode. Until 1950 this field was called
"radio technology" because its principal application was the design and
theory of radio transmitters, receivers and vacuum tubes."

Electrons never failed us.
