So, does an electron emit electro-magnetic radiation when it is moving at a constant velocity, and in a straight line?
So the parts of your questions I can answer are: 1) "does an electron emit electro-magnetic radiation when it is moving at a constant velocity, and in a straight line?"
Line-of-sight propagation refers to electro-magnetic radiation or acoustic wave propagation.
Most modern doodlebugs operate on a gravity principle, or they detect electro-magnetic radiations of obscure sorts which emanate from the oil.
All warm bodies emit electro-magnetic radiation: see thermal radiation.
Plastic, wood and china, all invisible to microwaves, will normally not get hot from electro-magnetic radiation.
Later, I wrote a somewhat critical review of his plan and sought to draw him out by reviewing the properties of electro-magnetic radiation in all parts of the spectrum.
Photoconductivity - The phenomenon in which a material becomes more conductive due to the absorption of electro-magnetic radiation such as visible light, ultraviolet light, or gamma radiation.
He also made very accurate measurements of propagation velocity of electro-magnetic radiation at radio frequencies and studied applications of radar in meteorology.
As the electrons pass through specially designed magnets at each vertex, their sudden change of direction causes them to emit an exceptionally bright beam of electro-magnetic radiation.
