Abstract
ESTE APARATO, DESTINADO A MEDIR EL VALOR DE UNA MAGNITUD FISICA QUE AFECTA A LA IMPEDANCIA DE UNA ESTRUCTURA ELECTRICAMENTE RESONANTE, COMPRENDE UNA ESTRUCTURA ELECTRICAMENTE RESONANTE, UNA FUENTE DE ENERGIA ELECTRICA DE FRECUENCIA RADIOELECTRICA, UNA LINEA DE TRANSMISION BIDIRECCIONAL DE FRECUENCIA RADIOELECTRICA QUE UNE DICHA FUENTE A DICHA ESTRUCTURA, UN ACOPLADOR DIRECCIONAL ASOCIADO A LA LINEA DE TRANSMISION Y SE CARACTERIZA POR QUE LA FUENTE PRODUCE UNA SEÑAL DE EXCITACION DESTINADA A LA ESTRUCTURA, PORQUE EL ACOPLADOR DIRECCIONAL DETECTA LA TENSION O LA FASE DE UNA SEÑAL REFLEJADA Y LA REENVIA A PARTIR DE LA ESTRUCTURA RESONANTE, POR QUE LA ESTRUCTURA RESONANTE NO PRODUCE PRACTICAMENTE UNA ENERGIA RADIANTE, Y PORQUE, A UNA FRECUENCIA DETERMINADA DE LA FUENTE, DICHA ESTRUCTURA TIENE UNA IMPEDANCIA VARIABLE Y CONTINUA EN FUNCION DEL VALOR DE LA MAGNITUD FISICA. GENERALMENTE, ESTA ESTRUCTURA RESONANTE ESTA, AL MENOS PARCIALMENTE, COMPUESTA DE MATERIALES PIEZOELECTRICOS.
