Abstract

Die Erfindung betrifft einen Reflektor mit geformter Oberfläche für elektromagnetische Wellen, wobei eine lokale Formgebung des Reflektors (1) derart ausgelegt wird, daß der Reflektor (1) mehrere, räumlich getrennte Foki (10a, 10b, 110a, 110b) aufweist. Es können dadurch von räumlich getrennten Strahlern (4a, 4b, 40a, 40b) ausgehende elektromagnetische Strahlbündel (5a, 5b, 50a, 50b), insbesondere solche verschiedener Frequenz oder Frequenzbänder, die den Reflektor (1) ausleuchten, auf ein gemeinsames Ausleuchtgebiet (3, 3a, 3b) gerichtet werden.
