چکیده

در کار حاضر، رفتار یک بلور نوری پلاسمایی یک‌بعدی در مواجهه با امواج الکترومغناطیسی مورد بررسی قرار می­گیرد. این بلور نوری شامل تناوبی از لایه­های دی­الکتریک و پلاسماست که در معرض یک میدان مغناطیسی ثابت خارجی می­باشد. میدان مغناطیسی در جهت تناوب لایه­ها قرار گرفته و فرود موج به بلور نوری به‌صورت مایل و تحت زاویه  خواهد بود. موج فرودی با قطبش خطی در عبور از لایه پلاسمای مغناطیده به دو دسته‌ی قطبش دایروی راست‌گرد و چپ‌گرد تفکیک می­گردد که این ناشی از تفاوت سرعت امواج راست‌گرد و چپ‌گرد در راستای میدان مغناطیسی می­باشد. ما پلاسما را در تقریب سرد ضعیف یونیزه در نظر می­گیریم و اثر برخورد الکترون­ها و ذرات خنثی در  پلاسما به‌عنوان یک اثر اتلافی که باعث جذب بخشی از انرژی موج می­شود، در محاسبات وارد می­گردد. ­ اثر شدت میدان مغناطیسی اِعمالی، فرکانس برخورد، ضریب گذردهی دی­الکتریک و زاویه فرود موج تابشی بر ساختار نوار فوتونی و ضرایب بازتاب و جذب بررسی می­شود.

چکیده [English]

The behavior of a one-dimensional plasma photonic crystal in exposure to electromagnetic waves is investigated in this paper. This photonic crystal consists of alternating layers of dielectric and plasma which are exposed to an external fixed magnetic field. The magnetic behavior of a one-dimensional plasma photonic crystal in exposure to electromagnetic waves is investigated in this paper. This photonic crystal consists of alternating layers of dielectric and plasma which are exposed to an external fixed magnetic field. The magnetic field is placed in the direction perpendicular to the layers, and the incidentwave on the photonic crystal will be obliquely and at an angle of . The incident linear wave passing through the magnetized plasma layer is separated into two categories of right-handed and left-handed circular polarization, which is caused by the difference in the speed of the right-handed and left-handed waves in the direction of the magnetic field. We consider the plasma to be a weakly ionized cold approximation and the effects of the collision of electrons and plasma molecules as a dissipation effect that absorbs part of the wave energy, is included in the calculations. We will investigate the effect of magnetic field intensity, collision frequency, dielectric permittivity and incident angle of radiation wave on the structure of the photon band, reflection and absorption coefficients. Plasma photonic crystal, Magnetized plasma, Right-handed circular polarization, transfer matrix, Collision frequency, Photonic band structure, Photonic band structure, reflection coefficient.
