Noun

Poynting vector ‎(plural Poynting vectors)

1. The vector obtained in the direction of a right-hand **** from the cross product (vector product) of the electric field vector rotated into the magnetic field vector of an electromagnetic wave. Note: The Poynting vector, with transmission media parameters and constants, gives the irradiance and direction of propagation of the electromagnetic wave. Mathematically: P = E × H.
