Add Terman to Kraus. On page 1 of Terman`s 1955 opus Terman says:
"Electrical energy that has escaped into free space exists in the form
of electromagtnetic waves. These waves, which are commonly called radio
waves, travel with the velocity of light and consist of mahnetic and
electric fields that are at right angles to each other and also at right
angles to the direction of travel."

That would interest me. I worked four years in a European shortwave
broadcast station and I don`t remember any frequency doubling but we
aspired to hit the ionosphere with enough power to drive it into extreme
nonlinearity end impose our signal en all the others in the area ala
Luxembourg.
