Dielectric/Conductor Interface

[megan]

How do I compute the electric Field, polarization and flux density at the interface of a dielectric material and a conducting Material?

[Claude Bile]

Use Maxwell's equations with the appropriate boundary conditions. Without any additional information, that is about the best answer I can give.

Is this question in the context of Capacitors, or does it have a connection with Surface Plasmon Resonance?

Thanks Claude

In regards to the conditions of Megans question the question just states that there is a bound surface charge density sigma b, and a free surface charge density sigma f.


So how do I use that in Maxwells equations?

[Claude Bile]

You can find the tangential and perpendicular components of the electric field at the boundary using the boundary conditions.

Think about how the D vectors on both sides of the interface are related at the interface.
