As you reject Postulate 4 explicitly in your statement(s), ...

Richard, you really need to grasp the difference between exclusive
and inclusive statements. Keith implies a voltage-only wave. It
is my understanding that an EM wave cannot exist without an
associated H-field. Chipman doesn't say EM waves can exist
without an H-field. EM waves possess both E-fields and H-fields.
The power associated with an EM wave is E x H. An H-field around
a wire implies a current in that wire. My objection to Keith's
statement is his voltage-only wave existing without current, energy,
or power.
