The two-dimensional Fig. 2-2 graph is confusing in that it could be
inferred that the E and H fields are 90 degrees out of phase in time
and are never zero at the same time. The E and H fields are in phase
in time as demonstrated by Fig. 2-4.

Hmmm. *I'm no expert, but I thought they were 90 degrees out of phase.
It's the rapidly changing H field that creates the E field and vica
versa. *If you look closely, Fig 2-4 also shows them 90 degrees out of
phase.

To the OP, heat is not electromagnetic radiation. *Light and x-rays
are. *You can heat something by pointing em radiation at it and
something that is hot gives off infra-red em radiation, but heat
itself is not em radiation. *

It is accepted that radiation is "an acceleration that generates or
transfers a charge ". This is an empty statement if one cannot explain
the mechanics of the operation.Certainly you have to determine what
you have in hand to provide this action, and at the present time there
is no agreement whether it is a wave flow of a constituent, what ever
that may be, or a particle.
Therefore one has to determine exactly what we are going to accelerate
and how we are going to avoid the effects of gravity since radiation
does not follow the action of a descending lob.
This as yet has not been determined, so we cannot begin to
understand! For me I see a wave as being an adjective and a particle
as a noun.
But a word of warning,physicists do not follow the same rules of the
general public, so if you have a day or two to spare get a physicist
to explain exactly what a 'wave' is and how does it fit with the
required straight line accelerating trajectory that opposes gravity!
You just cannot explain "radio" until you determine what you are
accelerating and how.
Sorry about that
