Poynting vector

Electrical engineering, Electromagnetism, Engineering, Natural sciences, Physical sciences, Physics The vector obtained in the direction of a right-hand screw 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.
