Part I - extraordinary transmission through nano-hole arrays

Animation shows EM intensity distribution 5 nm above a silver nano-hole array. This array is made of 100 nm in diameter cylindrical holes in 50 nm thin silver film. The array exhibits three very well defined resonances in transmission spectra -- this particular animation corresponds to the surface plasmon mode.

i have the very same question regarding the "non constant field change" in time... is it a pulse and besides please identify the angle of incidence as well...

Thanks alot

@rattinyou, pulse, normal incidence :-)

[K1audiafatu]

can you please explain me this simulation? the silver film is in the x-y plane and the light beam transmission occurs in the z direction? what we see is the energy transmitted (light colors= major energy density right?)

and why it is not constant in time? it is becouse you send an impulse and not a constant beam towards the film?

thank you very much and excuse my english!
