Optcal trap formation in a multi-slit system

Time-evolution of EM intensity in case of SPP resonance [anti-symmetric mode to be more precise] for a multi-slit silver film. After several optical cycles an optical trap is formed in the center of the slit [looks like a black pinhole]. It is very narrow with a huge field gradient allowing to trap a single atom.

Which wavelength did you investigate (visible range) and is this done with matlab? With FDTD? And what means SPP? Thank you :)

@Jinjukei, it's ultraviolet [around 400 nm]. The simulations were done using home-build FORTRAN codes. SPP stands for surface plasmon-polariton.

Is this a computer simulation? How was this made?

Exact solution of Maxwell equations in the presence of silver metal film exposed to external laser radiation.

looks nice, yet a reference would be real good to read what is going on here...

[Jinjukei]

Ok if have found your website ... :-)

So this is made with computer graphics? What are the equations? Showing the equations will help newbies.
