Аннотация
Сформулирована математическая постановка задачи об одноволновом безотражательном покрытии на основе метаповерхности. Построена область допустимых значений геометрических параметров структуры. Предложена штрафная функция, благодаря которой обеспечивается применимость физической модели, а искомый минимум становится единственным. В качестве примера рассмотрена задача о безотражательной метаповерхности из шариков PbTe, помещенных на германиевую подложку. Рассчитан спектр отражения такой структуры в диапазоне 8-12мкм. Проведено сравнение со спектрами метаповерхности без подложки и только одной подложки.
