Abstract

um transdutor acústico eletromagnético (4) inclui um guia de fluxo (8) circundada por um ou mais ímãs permanentes (10) em contiguidade com faces laterais do guia de fluxo (8). o campo magnético dos ímãs permanentes (10) entra no guia de fluxo (8), em que a repulsão entre os campos magnéticos direciona pelo menos uma porção dos campos magnéticos em direção a uma face de teste em contiguidade com um objeto de teste (2). a densidade de fluxo na face de teste é maior que a densidade de fluxo dentro dos ímãs permanentes de origem (10). uma porção ativa de uma bobina (12) disposta entre o guia de fluxo (8) e o objeto de teste contém condutores que são substancialmente retos, paralelos e portam uma corrente na mesma direção a fim de fornecer excitação substancialmente de modo puro e polarizada de modo unidirecional de ondas de cisalhamento dentro do objeto de teste.
