Dynamic Electric Currents Equations
In the Frequency Domain and Time Dependent study types dynamic formulations accounting for both conduction currents and displacement currents are used.
Combining the time-harmonic equation of continuity
with the equation
and generalized to handle current sources yields the following equation:
For the transient case, using the transient equation of continuity
and generalized to handle current sources the resulting equation becomes:
(2-18)
In planar 2D the dynamic formulations also involves the thickness d in the z direction:
