Calculation of Electric and Magnetic Field by Means of the Method of Tubes and Slices
Variational methods are often preferred in the calculation of electromagnetic field problems. They rely on the fact that the field as a system can be described by global parameters which have a stationary value when the system is varied in a prescribed manner. The parameters are generally formulated in terms of energy and the variational method explores the behaviour of the energy near its equilibrium value. Typical energy functionals are expressed in terms of circuit quantitites such as resistance, inductance and capacitance.
