Transmission spectra for array of nanoholes


Actually , i am trying to simulate the square periodic array of nanoholes on thin metal film of Au or PEC on glass(SiO2) substrate. I have attached the files of my structure and simulation results but it is not coming right for some wavelengths.

As u can clearly see my there should me some peak transmittance for Au film near 550 nm but it is not there in my simulation results.


Hi @krishna.sc16b087

Can you please share your simulation files for a review?

In the mean time, you can run multiple simulations with reduced source bandwidth as part of convergence testing and check the material fitting to make sure that it matches with the references.
