Hi everyone,
I am trying to simulate the penetration depth of light into gold. From
previous discussion I know that to do this, resolution in the order of
lambda/1000 is needed. As the limitation of my computer, however, I
cannot use such a high resolution. So I tried to calculate the flux in
the depth of 0.25*lambda which is much deeper than the penetration
depth of gold, and the result I got is around 0.001 times of the flux
on the surface, but the result I expected to get should be much
smaller than that.
What is your geometry ? In SPR geometry conditions flux may be even
higher. Also check how do you set up the properties of gold.
Lambda/1000 probably is too much - I see surface plasmons for
p-polarisation and no plasmons with s-polarization (as expected) already
at ca labmda/50.
WBR,
Shawkat
