Предложена более простая, по сравнению с предложенными ранее, модификация устройства маскировки объектов (двумерной невидимости обтекания), использующая положительную однородную анизотропную среду. Теоретический анализ и численное моделирование показали, что предложенная модификация невидимости обтекания обеспечивает проникновение внешней электромагнитной волны в маскируемую область, не нарушая в то же время маскирующего эффекта для внешних наблюдателей. Обсуждаются особенности конструкции, приведены результаты моделирования.
Ключевые слова: невидимость обтекания, оптические преобразования, метаматериалы.
A two-dimensional invisibility anti-cloak constructed by positive homogeneous anisotropic medium is proposed, which is easier to implement compared with reported invisibility anti-cloak structures. Theoretical analysis and numerical simulations show that the proposed invisibility anti-cloak can make the external electromagnetic waves penetrate into the cloak region, while the concealing effect of invisibility cloak is not affected for the outside viewers. Design details and full-wave simulation results are provided.
Keywords: anti-cloak, transformation optics, metamaterial.
