| چکیده | ||
| فناوری پلاسما در بسیاری از کشورها در زمینه‌های مختلفی مانند تولید ازن، تصفیه سطح، اصلاح سطح، پزشکی و غیره استفاده می‌شود. پلاسمای تولیدشده با امواجی مانند مایکروویو، یک فناوری امیدوارکننده و جالب برای ویژگی‌های منحصر به فرد و همه کاره آن است. این ویژگی‌های پلاسمای مایکروویو یک فناوری جایگزین در مقایسه با راکتورهای شیمیایی حرارتی سنتی به شرط رفع چالش‌های فنی خاص آن است. در این مطالعه عددی، خواص پلاسمای مایکروویو با فرکانس 45/2 گیگاهرتز و گاز آرگون در فشار اتمسفر بررسی شد. با تغییر توان ورودی دستگاه در محدوده 10 وات تا 20 وات در حالت مغناطیسی و مد (TM)، پروفایل‌های مقایسه‌ای چگالی الکترون، دمای الکترون، میدان الکتریکی نشان داده می‌شود. نتایج شبیه‌سازی، تولید المان‌های شیمیایی در پلاسمای مایکروویو را نشان می‌دهد. الکترون‌های پرانرژی و چگالی الکترون به‌عنوان عوامل اصلی مؤثر بر خواص پلاسمای مایکروویو در نظر گرفته شده‌اند. | ||

| چکیده [English] | ||
| Plasma technology is widely applied in various domains, including ozone generation, surface treatment, surface modification, medicine and more. Microwave-induced plasma is a promising and interesting technology due to its unique and versatile properties. These features of microwave plasma is a potential alternative to conventional thermal chemical reactors, provided that specific technical challenges are addressed. This numerical study investigated the characteristics of a 2.45 GHz microwave plasma generated in argon gas under atmospheric conditions. By varying the input power of the device from 10 to 20 watts within a magnetically confined TM mode, comparative profiles of electron density, electron temperature, and electric field were analyzed. The simulation results demonstrate the production of chemical species within the microwave plasma. High-energy electrons and electron density were identified as primary factors influencing the microwave plasma's properties | ||
