      Good afternoon,

      How can I do a transmission spectrum like the one of the attached image? It is a plot of normalized transmission versus wavelength, I am using the 32bit free version. The structure is like one of the tutorials, the example simulate wavelength holes in a metallic film.

      Regards

      Miguel Simoes

      This is one of the core features of OptiFDTD. Check out this tutorial on photonic crystals:

      Cheers!

      Hello!

      Thanks very much for the answer, but to calculate the transmission spectrum, transmission versus wavelength, can I only use observation points or can I use observation areas too? For me I think that it will be more useful observation areas.

      Regards

        You can use both, but yes you would want to use an area detector to find the normalized transmission.

      Hi Miguel,
      I think in this case you should used multilayer structures of quarter-wave stacks. Each additional stack will broaden your area.
