John Wiley The Power And Beauty Of Electromagnetic Fields by Frederic R Morgenthaler
In this text, the author develops alternate representations of electromagnetic power and energy that differ form the familiar Maxwell–Poynting theorem values (S and W) – yet are fully equivalent. The particular choice focused on features highly–localized power and energy components and emphasizes the circuit rather than the wave nature of these quantities. Moreover, unlike the Poynting vector, this exact representation merges smoothly with well–known quasistatic approximations that have long been used to calculate power flows in both lumped and distributed circuits operating at low–frequencies.
