About this document

Time-Averaged Poynting Vector Derivation by Pa Blo is a document available to read on EtoBox.

The Poynting vector describes the flow of electromagnetic energy. It is defined as the cross product of the electric and magnetic fields. Using phasor notation, the document expresses the Poynting vector in terms of the real and imaginary components of the electric and magnetic fields. Upon time-averaging, the cross terms involving sinusoidal functions average to zero, leaving an expression for the time-averaged Poynting vector in terms of the real parts of the inner product of the complex conjugate fields.
