Abstract

LA INVENCION PRESENTA UN METODO PARA LA FABRICACION O PRODUCCION DE LENTES TRIDIMENSIONALES CON UN INDICE DE REFRACCION VARIABLE POR ENVOLTURA DE UN MATERIAL CON UN INDICE DE REFRACCION DADO. SE PREFIERE QUE ESTE MATERIAL TENGA LA FORMA DE UN HILO QUE PODRIA SER CILINDRICO. LA FORMA PREFERIDA DE LA LENTE QUE SE VA A PRODUCIR ES ESFERICA O SEMIESFERICA, LO CUAL PUEDE SER LOGRADO POR UN PROCESO DE ENVOLVER APROPIADO O POR CORTE DE LA FORMA ESFERICA. POR EL METODO DE LA INVENCION ES POSIBLE PRODUCIR DICHAS LENTES CON UN INDICE DE REFRACCION SUAVEMENTE VARIABLE. SE PREFIERE EL USO DE LAS LENTES PRODUCIDAS COMO PARTE DE UN SISTEMA DE ANTENA PARA MICROONDAS.
