Abstract

Una disposicion de imanes disenada de componentes flexibles y materiales puede conformarse facilmente para ajustarse al contorno de varias superficies curvadas y estructuras. Los EMAT que incorporan estos imanes, ademas de ser flexibles, pueden ser mas pequenos en volumen que los imanes de EMAT convencionales y por lo tanto mas faciles de aplicar a estructuras complejas donde puede restringirse el acceso. Tambien, las disposiciones de imanes de varios polos flexibles pueden fabricarse facil y economicamente en varias conformaciones y configuraciones, incrementando por consiguiente la versatilidad, utilidad y efectividad de costo en comparacion con los disenos de imanes convencionales rigidos.
