Abstract
SE PRESENTA UN TRANSPONDEDOR PARA UN SISTEMA DE DETECCION QUE COMPRENDE UN TRANSMISOR, PARA LA PRODUCCION DE UN CAMPO MAGNETICO ALTERNANTE QUE TIENE UNA FRECUENCIA PREDETERMINADA, Y UN RECEPTOR. EL RECEPTOR ESTA PROVISTO DE UN DETECTOR QUE ES CAPAZ DE DETECTAR LAS ARMONICAS MAYORES PREDETERMINADAS DE LA FRECUENCIA DEL CAMPO ALTERNANTE. EL TRANSPONDEDOR COMPRENDE UN ELEMENTO DE SEÑALES HECHO DE UN MATERIAL SUAVEMENTE MAGNETICO. CUANDO EL TRANSPONDEDOR SE CONOCE EN EL CAMPO ALTERNANTE MAGNETICO, LAS ARMONICAS MAYORES DE LA FRECUENCIA DEL CAMPO ALTERNANTE SON GENERADAS POR EL ELEMENTO DE SEÑALES. EL ELEMENTO DE SEÑALES TIENE LA FORMA DE UN CIRCULO.
