resonance strange shape

reflection

#1

I still find the straight line behaviour of the Reflection at low wavelengths very strange. please, look at the graph attached.

the simulation is also attached

Dear @hamada

Can you please explain what are those two plots? Are they for a single simulations? and also why the result is strange?

Thanks

Hi @hamada
Did you mean that the blue line graph comes from the one simalation file and the green one from the other simulation file ?


#4

yes the blue graph is from a simulation file with background index=1.33 and the green one is from another file with background index =1.34


#5

Hi @hamada

Can you please explain what you were expecting to see in shorter wavelength and provide explanation/references to confirm your idea?

Thanks
