ملخص المقالة :
در اين مقاله، روش معادله سهموي براي حل مسأله انتشار امواج از درون ساختارهای پنجره‌ای مورد استفاده قرار ميگيرد. با استفاده از اين روش مسأله انتشار امواج از داخل يك مجموعه پنجره براي حالت‌هاي مختلف حل می‌شود و چگونگی تأثیر ابعاد پنجره‌ها بر پرتو پراش حاصل بررسی می‌گردد. نتايج حاصل از اعمال روش معادله سهموي براي مسأله ذکرشده در حالت‌های تابش عمودی و مایل امواج صفحه‌ای یکنواخت و نایکنواخت ارائه شده و با نتایج حاصل از روش FDTD موجود در مراجع در حالت تابش موج صفحه‌ای یکنواخت مقایسه می‌شود. با توجه به تشابه زیاد نتایج حاصل از این دو روش، از آنجا که روش معادلات سهموي نسبت به روش FDTD به زمان محاسبات و حافظه كامپيوتر كمتري نياز دارد، ميتواند شيوه مناسبي براي حل چنين مسائلي باشد.
