ELECTRIC FIELD INTENSITY (E)
MAGNITUDE OF E: Proportional to the force acting on a unit positive charge at a point in the field
DIRECTION OF E: The direction that the force acts
The Electric Field (E) is represented by drawing the Electric Displacement Vector (D), which takes into account the characteristics of the medium within which the Electric Field exists.
The Magnetic Field (H) is represented by drawing the Magnetic Induction Vector (B), which takes into account the characteristics of the medium within which the current flows.
Anomalous Propagation
The propagation of a radar ray along a path other than that associated with standard atmospheric refraction
