Abstract

Un silenciador de metamaterial bicapa permite fluido sustancial a través del aparato, mientras mitiga la propagación de sonido a través del aparato, y mientras proporciona un factor de forma que es significativamente más compacto que los dispositivos previamente conocidos; además, las modalidades ilustrativas permiten que un diseñador especifique una o ambas de la frecuencia o frecuencias a las que el aparato mitiga la propagación del sonido, y/o el ancho de banda alrededor de la frecuencia o frecuencias a las que el aparato mitiga la propagación del sonido.
