Abstract
Raziskovalci so na področju nizkotlačne plazemske tehnologije v zadnjih desetletjih uspešno razvili rešitve za mnoge probleme v industriji, agronomiji in biomedicini. Ker je pri dani plazmi možnih interakcij delcev veliko, je težko vnaprej natančno predvideti, kako se bo obnašala določena reaktorska postavitev. Tu nam lahko pomaga računalniška simulacija, s katero je mogoče enostavno oceniti različne parametre v hipotetičnem plazemskem reaktorju. V programu za fizikalno modeliranje COMSOL Multiphysics smo sestavili model induktivno sklopljenega reaktorja ter z njim preko metode končnih elementov izračunali nekatere plazemske parametre. Rezultate smo primerjali z meritvami argonove plazme, izvedenimi z Langmuirjevo sondo v dejanskem reaktorju.

Title:Simulating low-pressure plasma with the finite element method
Abstract:
In the last few decades, researchers from the field of low-pressure plasma technology have successfully developed solutions for many problems in industry, agriculture and biomedicine. For a given plasma, there exists a large number of possible particle interactions, so it is hard to accurately predict how a specific reactor configuration will behave. Computer simulation can be used to easily approximate different parameters in a hypothetical plasma reactor. A model of an inductively coupled reactor was constructed in COMSOL Multiphysics and used to calculate certain plasma parameters using FEM. The results were compared with Langmuir probe measurements of argon plasma in the physical reactor.

Keywords:low-pressure plasma, plasma modeling, finite element method, COMSOL Multiphysics
