hi guys..
I'm trying desperately to solve the following Helmholtz equation:
*(all parameters are known)
[tex]
\frac{\partial^2 E_z}{\partial x^2}+ \frac{\partial^2 E_z}{\partial y^2} +j\omega\sigma E_z=0
[/tex]
(Ez is a scalar of course)
in the boundaries -inf<x<inf, -inf<y<0
with the following boundary conditions:
Ez(y->-inf)=0; [tex] Ez(y=0)=\frac{jwI}{4*pi}*log(\frac{(d+x)^2+a^2}{(d-x)^2+a^2}) [/tex]
Ez(x->inf or -inf)=0
the proposed solution is of the form Ez=sin(Kx*x)*exp(Ky*y)
the main problem here is to find a sine/Fourier series expansion of the boundary condition.
anyone have an idea??
