Abstract
Un circuito reflector para recibir radiación (4) de iluminación y emitir una correspondiente radiación amplificada (6) de salida , cuyo circuito comprende: - un conjunto de antena (2) para recibir la radiación (4) de iluminación y suministrar una señal recibida correspondiente, y - medios de tratamiento (8, 10;8, 10, 102, 104, 106 y 108) para amplificar y almacenar una fracción de la señal recibida durante un período de tiempo con el fin de utilizarla en la generación de una señal correspondiente de salida para emitirla desde el conjunto de antena (2) como la radiación (6) de salida, caracterizado porque los medios de proceso están dispuestos de manera que proporcionen amplificación selectiva de frecuencia (1, 100, 200 y 300) en respuesta a la magnitud de los componentes presentes en la radiación (4) de iluminación .
