Greetings Everyone,
Assume I have a surface S that is a PEC (perfect electric conductor -
lossless) with a surface current J and surface charge p. J is of
course a vector field and p is a scalar field.
We can write J as pv where v is a vector that represents the velocity
of the net flow of charge (p is the same as before).
If I take the gradient of p, what can be said about the angle between
J and grad(p) for all points on S? More importantly, what can be said
about v and grad(p) ? I am wondering if one can somehow show that in
general these two vectors are parallel, or perhaps for some special
cases they are parallel.
Thank you for your time. |
