Благодаря своим уникальным свойствам терагерцовое излучение используется для решения широкого спектра задач в спектроскопии, дефектоскопии и обеспечения безопасности. Создание эффективных поглотителей и преобразователей терагерцового излучения является сейчас основой для развития терагерцовых технологий. В настоящей работе рассматривается использование частотно-избирательного высокодобротного метаматериала для создания конвертера терагерцового излучения в инфракрасный диапазон длин волн. Предложен конвертер, состоящий из метаматериального поглотителя терагерцового излучения, покрытого микрометровым слоем графита, переизлучающим поглощенную метаматериалом энергию в инфракрасном диапазоне. Произведен численный электродинамический и сопряженный с ним тепловой расчет предлагаемого конвертера излучения. Результаты численного моделирования метаматериала на частоте 96 ГГц (окно прозрачности атмосферы) показали коэффициент поглощения электромагнитного излучения равный 99,998 %, а аналитически рассчитанный коэффициент полезного действия разработанного конвертера составил 93,8 %. Благодаря этому разработанный нами конвертер терагерцового излучения может найти применение в области досмотрового контроля в сфере транспортной безопасности и дефектоскопии.</p></abstract><trans-abstract xml:lang="en"><p>Since the early 1980s, the terahertz range (from 0.1 to 10 THz) attracts constant attention of both fundamental and applied physics. Due to its unique properties, terahertz radiation finds it’s applications in spectroscopy, defectoscopy, and security systems. The construction of efficient absorbers and converters in terahertz range is crucial for further development of terahertz technologies. In this work, we use a frequency-selective high-Q metamaterial to construct a converter of terahertz radiation into the infrared radiation. The converter consists of a metamaterial absorber of terahertz radiation covered with a micrometer thick layer of graphite, which emits in the infrared range the energy absorbed by the metamaterial. We have made a numerical electrodynamic and associated thermal simulation of the radiation converter. The metamaterial simulation at 96 GHz (low opacity window of the atmosphere) shows the electromagnetic radiation absorption coefficient of 99.998%, and the analytically calculated converter efficiency of 93.8%. Concluding the above our terahertz radiation converter may contribute to security systems and defectoscopy setups.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метаматериал</kwd><kwd>терагерцовое излучение</kwd><kwd>инфракрасное излучение</kwd><kwd>конвертер излучения</kwd><kwd>частотно-избирательная поверхность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metamaterial</kwd><kwd>terahertz range</kwd><kwd>infrared range</kwd><kwd>radiation converter</kwd><kwd>frequency selective surface</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы благодарят Малееву Н.А. за помощь в оформлении результатов данного исследования в научную статью.
