Hello everyone,
I work with polymer materials and I am attempting to model optical parameters (refractive index) and dielectric parameters (dielectric permittivity). Since I am not very familiar with this type of modeling, I am reaching out to you to inquire about possible approaches for creating mathematical models to estimate these parameters in the frequency range of Giga and Terahertz.
Best regards,
Hi Abdelaaziz Benoudina,
The long-term molecular dynamics simulation may be useful to you. However, studying the dielectric response of polymer is a challenging work.
Please find the following reference. Although it is a investigation of ceramic, not polymer, I think it will inspire you.
Wang, D., Bokov, A., Ye, ZG. et al. Subterahertz dielectric relaxation in lead-free Ba(Zr,Ti)O3 relaxor ferroelectrics. Nat Commun 7, 11014 (2016).
Polimer malzemenin optik ve dielektrik parametrelerin modellemesinde, kırılma indisi optik malzemeler için ayırt edici, dielektrik sabiti elektrik iletkenliği olan malzemeler için ayırt edici bir özellik olur.
Not sure if I completely understand your requirement. Are you already modelling it with the Sellmeier Formula?
