| چکیده | ||
| در این مقاله، یک ساختار ناهمگن از گرافن به عنوان جاذب کامل چند باندی در محدوده تراهرتز و به صورت مستقل از پلاریزاسیون طراحی شده است. این ساختار شامل سه لایه مس، دی اکسید سیلیکون و گرافن ناهمگن به همراه آنالیت میباشد. با تغییر ابعاد لایههای زیرین و شکل هندسی برشهای گرافن، میتوان تعداد باندها، کیفیت و میزان جذب را تنظیم کرد. همچنین، با تغییر پتانسیل شیمیایی گرافن، امکان تنظیم فرکانسهای جذب به مقادیر دلخواه وجود دارد. این ساختار میتواند در حسگرهای بیولوژیکی برای شناسایی پروتئینها، ویروسها و سلولهای سرطانی، همچنین در کاربردهای مخابراتی و تصویربرداری مورد استفاده قرار گیرد. برشهای هندسی گرافن در فرکانسهای THz 4.99، THz 9.21، THz 10.5 و THz 11.7 به ترتیب جذبهایی معادل 99.6، 99.3، 99.6 و 94.7 درصد را به دست آوردهاند. قرار دادن آنالیت بر روی ساختار پیشنهادی موجب تغییر در مقادیر فرکانس جذب میشود که این تغییر به دلیل تفاوتهای ضریب شکست مواد مختلف است. از این ویژگی مهم در طراحی حسگرهای زیستی بهرهبرداری شده است. بالاترین میزان حساسیت در باند سوم GHz / RIU 994 مشاهده میشود که با توجه به ساختار ساده متشکل از سه لایه و استفاده از مس به جای طلا، و همچنین مقایسه نتایج این تحقیق با مطالعات قبلی، میتواند بهترین گزینه برای ساخت حسگر زیستی باشد. یکی از ویژگیهای کلیدی این سازه این است که به قطبی شدن حساس نیست. شبیهسازیها با استفاده از نرمافزار شبیهسازی کامپیوتری (CST) انجام شده است. | ||

| چکیده [English] | ||
| In this paper, the heterogeneous structure of multi-band perfect absorbing graphene in the terahertz range is designed independent of polarization. The proposed structure consists of three layers of copper, silicon dioxide and heterogeneous graphene structure and analyte. By changing the dimensions of the sub-layers and the geometric shape of the graphene slices, the number of bands, the quality, and the amount of absorption can be changed. Also, by changing the chemical potential of graphene, the absorption frequencies can be adjusted to the required values. The application of this structure in biological sensors is to detect proteins, viruses, cancer cells, telecommunication waves and imaging. With the cuts made on graphene in geometric shapes at the frequencies 4.99 THz, 9.21 THz, 10.5 THz, and 11.7 THz, absorption values of 99.6, 99.3, 99.6 and 94.7% have been obtained, respectively. placing the analyte on the proposed structure causes the displacement of the absorption frequency values, which is due to the different values of the refractive index of different materials. This important property has been used for biosensor design. The highest sensitivity value in the third band is994GHz/RIU, which due to the simple structure consisting of three layers and the use of copper instead of gold, and also by comparing the output values of this research with previous research, can be the best option for making a biosensor. One of the important features of this structure is that it is not sensitive to polarization. The simulations were done in computer simulation software (CST). | ||
