Termn`s writings have been exposed for anyone to criticize for most of a
century. His 1955 edition has been out there for 50 years. No
retractions or corrections are necessary.

Detection of static E-fields is not relevant.
Charles Coulomb in 1785 showed electric charges exert forces on each
other that are inversely proportional to the square of the distance
between them. This was the birth of the "inverse square law" as
Coulomb`s discovery applies to magnetic attraction and repulsion, too.

In an electromagnetic field, propagation depends upon the electric field
begetting a magnetic field and vice versa. On average, each field
contains 50% of the total energy.

The electromagnetic field of an antenna could be calculated from the
distribution of voltage on the conductors. Problem is voltmeter leads
would be in the r-f field and this would tend to make measured voltages
inaccurate. R-F current is conveniently and accurately measured with a
thermocouple ammeter.

Strength of an electromagnetic wave is usually measured and quoted in
terms of its electric field in volts per meter. This is the number of
volts which would be induced in a one-meter length of wire placed in the
field parallel to the electric lines of force. Volts in the wire are
produced by movement of magnetic flux across the wire.
