HELP:Calculating EM field using Laplace's eqns.
B.S.Ong
Need a little bit of help.
I am working on an educational package to teach undergraduates
the principles of EM.
I am using Laplace's equations to evaluate the potential at any
given point in free space (e.g. box problem with any arbitrary
combination of potential boundaries). How can Laplace's equations
be used on problems containing regions of varying relative
permittivity (a typical example is the microstrip line where
the conductor carrying a current is seperated from the ground plane
by an insulator)?
After evaluating the potential and electric fields, how can the
capacitance of the line (with and without dielectrics) and the
energy stored be calculated?
How are line and surface integrals related to the above box problem?
What are the purposes and how can they be done.
It would be helpful if you could recommend me text which are easy
to understand.
Thanx in advance.
Regards,
Ong
