Dear Prof. Ishijima

In plasma applications with commercial CST Microwave Studio , you can obtain or assume the existence of plasma relying on Drude model. In which you identify the plasma frequency with selected (given) plasma density value. The assumed plasma parameters independent of the frequency and power of the exciting wave.

Dear Prof. Essam Abdel-Fattah, Thank you for your reply. We would like to know how to obtain plasma density technically from the CST STUDIO SUITE 2018. In the attached pdf, page 23, plasma density [1[PowRMS, 0.0],[2.5]] was obtained as an absolute value. However, we could not find "Abs component" from the menu. Let us check the functions carefully again. Thanks.

The plasma density distribution shown in page 22, is a calculated pattern. The plasma density distribution relate linearly with the local electric field. I think, changing the Breakdown Voltage value and plasma maintain frequency together with the input plasma frequency in Drude model will produce the plasma density distribution.

Hello,

Directly to calculate the plasma density is little bit difficult, but by calculating plasma frequency and other parameters, then it is easy, even though for microwave frequency, the there is change in Maxwell's equation when it comes under plasma conditions.

Few papers are attached.

Thanks,
