ملخص المقالة :
در اين مقاله روشي سريع براي شبيه‌سازي فرآيند گرمايش مايکروويو در مواد مخلوط به ويژه مواد آلي و ترکيبات نفتي معرفي مي‌شود. با بکارگيري روش FDTD در مواد واپاشنده و ارائه روش TD2(FD) که بر مبناي رابطه تلفيقي بين ميدان‌هاي E و D و يا بر اساس رابطه تفاضلي بين اين دو ميدان مي‌باشد مسئله فرآيند گرمايش مايکروويو مدل‌سازي و مشابه‌سازي شده است. با بکارگيري اين روش زمان طولاني و حجم حافظه زياد مصرفي براي تحليل محيط‌هاي واپاشنده بسيار بهبود پيدا کرده است. نهايتاً اين روش براي مشابه‌سازي فرآيند گرمايش مايکروويو در برخي از انواع نفت خام بکار گرفته شده و نتايج ارائه شده است.
