Rectangular Coordinates. Helmholtz Equation.

The Helmholtz equation for 1-D steady Green's Function in rectangular coordinates is:

$\displaystyle {\frac{d^{2}G}{dx^{2}}}$ - m2G = - $\displaystyle \delta$(x - x$\scriptstyle \prime$)    

Here quantity m (units meters-1) may represent side heat losses, as from a fin.
