Boundary value problem for non-conducting surface

Click For Summary
SUMMARY

This discussion focuses on solving boundary value problems for non-conducting surfaces in electric fields, specifically addressing the challenges faced when applying the method of images, typically used for conducting surfaces. The user highlights the lack of definitive solutions for non-conducting surfaces, such as wooden plates, and references Green's theorem as a theoretical foundation. A breakthrough was achieved by discovering a paper that outlines the effect of dielectric walls on electric fields, indicating that while more complex than conductive cases, solutions are attainable. The discussion also recommends Harrington's "Moment Method" textbook for numerical solutions to these problems.

I have dealt quite a lot with the boundary value electrostatics problem with a plane or spherical conducting surface in an electric field due to a single electric charge or dipole. This can be conveniently done using the method of images. Method of images simplifies a lot of things. Jackson's book has a lot of material on this.

But I have never come across anything like that for non-conducting surfaces, like a wooden plate in an electric field or so. Green's theorem gives the theory for this, but there appears to be no definite solution for this problem. I need to solve this problem for some research, but have hit a major roadblock.

Is this problem of a non-conducting plane surface in an electric field even solvable using a method of images -like formulation? Can some subtle changes in the conducting plane counterpart be made to achieve this particular solution? Can someone direct me to a book or a paper or class notes etc. that solves this problem?

Thanks

Well never mind. I found a way to find the effect of a dielectric or non-conductive wall on an electric field. It is slightly more involved than its conductive counterpart. Here is a paper that does this derivation http://iopscience.iop.org/0143-0807/21/6/305

It is sort of the like the method of images.
 
I would take a look at Harrington's Moment Method textbook. The method of moments can provide numerical solutions for these kinds of problems. There are of course other methods but in general I think your best bet is to do some form of numerical calculation.
