Abstract

Un dispositivo (10) para cambiar la divergencia de un haz de radiación electromagnética, que comprende un cuerpo (12) que tiene una abertura (28) electromagnética para el haz y unos medios magnéticos (20) dispuestos para generar un gradiente magnético a través del cuerpo (12) que actúa sobre el haz a medida que este atraviesa el cuerpo, caracterizado porque los medios magnéticos (20) actúan sobre la abertura electromagnética (28) de modo que hay un retardo de fase diferencial sobre la abertura electromagnética (28) desde una región central hasta a una región periférica de la abertura (28) electromagnética.
