Capacitance Simulation

This is a simulation of a single conductor above a ground plane. The simulation window is actually much larger to ensure proper boundary conditions.

Solving for magnetic fields in DEVSIM.

This past week I’ve been experimenting with solving magnetic field problems. Here is my first result. Two wires are in the center of the figure with current flowing in opposite directions. The solution variable is the magnetic vector potential, A, and is shown in the color gradient. The arrows are the magnetic field, B, which is post processed from the solution. In turns out this post processing is similar to finding the vector impedance field used in noise analysis.
