Abstract

EL SENSOR DE CAMPO DE DISPERSION DE MICROONDAS PARA LA MEDIDA DE HUMEDAD Y/O DENSIDAD DE COMPUESTOS DIOELECTRICOS SE CARACTERIZA PORQUE ESTA FORMADO ESENCIALMENTE DE UNA MANERA DE SIMETRIA DE ROTACION, EN DIRECCION AXIAL A AL MENOS UN LADO Y SIENDO PERMEABLE A LA RADIACION ELECTROMAGNETICA, Y QUE EN EL SE FORMA UN CAMPO ALTERNO DE ONDAS CONSTANTES EN UNA SIMETRIA ESNCIALMENTE ROTACIONAL, CUYOS PERIODOS DE ESPACIO SON MAS PEQUEÑOS EN LA DIRECCION DEL PERIMETRO QUE LAS LONGITUDES DE ONDA AL VACIO EN LA FRECUENCIA DEL CAMPO ALTERNO.
