Campos Magnéticos Influenciam Ondas Sonoras em Descoberta Revolucionária

Pesquisadores descobriram uma nova maneira pela qual ondas acústicas de superfície interagem com materiais magnéticos, levando a um surpreendente efeito de difração assimétrica. Isso pode revolucionar as tecnologias de comunicação baseadas em acústica. Crédito: SciTechDaily.com Ao experimentar materiais magnéticos em nanoescala, pesquisadores descobriram um padrão de difração assimétrico em ondas acústicas de superfície (SAWs) —...

Físicos Criam Ondas Sonoras que se Movem Exclusivamente em Uma Direção

Auto-oscilações (vermelha e azul) guiam ondas sonoras (verde, laranja, roxa) em apenas uma direção através do circulador. (Xin Zou) Imagine três pessoas dispostas em círculo, onde cada uma pode ouvir diretamente apenas outra pessoa. Cientistas criaram um dispositivo que direciona ondas sonoras exatamente dessa maneira, permitindo que elas viajem apenas em uma única direção. Desenvolvido por...
