چکیده

در این مقاله اثر ایجاد نقص متقارن مرکزی بر روی میزان عبور و چرخش فاراده در بلور فوتونی مگنتو اپتیک یک بعدی متشکل از دو ماده دی‌الکتریک و یک ماده مگنتو اپتیک مورد مطالعه قرار گرفته است. پس از اجاد نقص، اثر افزایش حجم نقص بر روی پهنای نوار گاف و تعداد مد‌های هدایتی دارای چرخش فاراده در ناحیه نوار گاف بررسی شده است. بیشترین چرخش به‌دست آمده در این ساختار 27- و بیشترین مقدار عبور حاصل شده 917/0 است.
