1. wich is the dielectric functtion used in the calculation?

Closed | Responses: 1

Is simply the bulk dielectric constant or is the corrected one by the Drude model?

2. will this help me to get light-nanoparticle interaction analysis of patterned tri-layers of gold-alumina-gold? (metamaterials))

Hi! What kind of dielectric function for silver and gold do you use in this method? I mean, it is drude model or experimental data or something else. Thank’s a lot for your reply!

4. question about starting and initial wavelength

Closed | Responses: 1

Hi, I was wondering what is the difference between initial wavelength in the simulation parameters and starting wave length in electric field. Is initial value represents the wavelength of...

Hi, Thank you for your interesting tools. I want to know which method you use to simulate, Mie theory? or FDTD?

6. hi, my simulation only gave extinction (absorption, scattering) spectrum but electric field did not come out, would anyone tell me why? thanks

7. Is there a mistake in the software?

Closed | Responses: 1

From the basics and references I made sure Extinction is fading of energy and is caused due to absorption and scattering. and their coefficients and also cross sections are related as...
