图书简介
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 focuses on features highly-localized power and energy components and emphasizes the circuit rather than the wave nature of theses 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.
