LONDRES. Un equipo de científicos británicos está cerca de desarrollar una innovadora “capa de invisibilidad” al estilo de la saga cinematográfica Harry Potter.




Los expertos dieron a conocer una película flexible de pequeñas estructuras que forman un “meta-material”, capaz de manipular la luz haciendo invisibles los objetos que cubre. Los “meta-materiales” flexibles ya habían sido creados en el pasado, pero sólo funcionaban con la luz de colores que el ojo humano no percibe.

La investigación británica, que fue dada a conocer en la revista especializada New Journal of Physics, fue calificada por los expertos como un “enorme paso” en la creación de la llamada “capa de invisibilidad”. Los “meta-materiales” son materiales artificiales que presentan propiedades electromagnéticas inusuales, procedentes de la estructura diseñada y no de su composición, es decir, son distintas a las de sus constituyentes.

Funcionan al interrumpir y canalizar el flujo de luz a un nivel fundamental específico, creando en algunos casos un desvío óptico de la imagen.

“El primer paso es imaginar que esto puede lograrse”, declaró Andrea Di Falco, profesor de la Universidad de St. Andrews (Escocia) y autor del informe.

En la saga literaria de Harry Potter, su autora JK Rowling creó para su personaje central la “capa de la invisibilidad”, capaz de hacerse y hacer invisible a quien se la ponga, y de proteger siempre a su amo.

No se ustedes pero a pesar de que se oye bien perro el concepto, no le encuentro mucho sentido, osea como pa'que querria yo una capa invisible?
