Hello,

I'm a math student, taking a particular math class where they

kind

of implicitly assume everyone has 4 years of physics (even though

they

aren't supposed to assume ANY physics). They basically just want

me to

solve a PDE-BC problem numerically using finite difference methods.
The problem is, the PDE-BC is buried deep in a physics paper which

is

miles over my head and which (of course) never explicitly says

"this is

our PDE-BC". The paper is Y. Tsuji and M. Koshiba, "Finite element
beam propagation method with perfectly matched layer boundary
conditions for three-dimensional optical waveguides", Int. J.

Numer.

Model. 2000; 13:115-126. Although the paper is long, I am told

that

everything needed to get the actual PDE-BC is within the first 4

pages.

I know it is asking quite a large favor, but if anyone could offer

any

help, even just a hint like "in physics ''blah'' is magic

moonlanguage

for ''this is our PDE-BC problem''", I would be extremely grateful.

Is this "International Journal of Numerical Modelling" or something
like that? Sorry, I don't find that in my local library, nor on the

web.

Could you please tell me where I can find the paper?

I can't find it either, though I've located what is
obviously an earlier version of the same material. A
paper by that title with authors Koshiba, Tsuji and Hikari
appeared in the 1999 IEEE Transactions.

method with perfectly matched layer boundary conditions," IEEE Trans.

"S.A." sent the article to me per e-mail in the meantime. Interested?
