Abstract

Un transductor electromagnético acústico (4) incluye una guía de flujo (8) rodeada por uno o más imanes permanentes (10) que están en contacto con las caras laterales de la guía de flujo (8). El campo magnético de los imanes permanentes (10) entra en la guía de flujo (8) donde la repulsión entre los campos magnéticos dirige, al menos, una parte de los campos magnéticos hacia una cara de ensayo que esta en contacto con un objeto de ensayo (2). La densidad de flujo en la cara de ensayo es mayor que la densidad de flujo dentro de los imanes permanentes (10) que la originan. Una parte activa de una bobina (12) dispuesta entre la guía de flujo (8) y el objeto de ensayo contiene conductores que son sustancialmente rectos, paralelos y transportan corriente en la misma dirección con el fin de proporcionar sustancialmente rectos, paralelos y transportan corriente en la misma dirección con el fin de proporcionar sustancialmente una excitación de modo puro y polarizada de manera unidireccional de las ondas transversales dentro del objeto de ensayo.
