Abstract

UN METODO PARA ALTERAR LAS PROPIEDADES DE UN MATERIAL FERROELECTRICO QUE TIENE UNA CONSTANTE DIELECTRICA (PERTENECE A) R, UNA TANGENTE DEL ANGULO DE PERDIDAS TAN (DELTA), UNA CAPACIDAD DE SINTONIZACION A UNA FRECUENCIA DADA F, QUE CONSISTE EN REDUCIR DICHA CONSTANTE DIELECTRICA (PERTENECE A) R Y DICHA TANGENTE DEL ANGULO DE PERDIDAS TAN (DELTA) AL TIEMPO QUE SE MANTIENE UNA FRACCION SUSTANCIAL DE DICHA CAPACIDAD DE SINTONIZACION, CON LO QUE SE OBTIENEN ESTRUCTURAS (21) DE DICHO MATERIAL FERROELECTRICO QUE SON ESENCIALMENTE UNI DONDE DICHAS ESTRUCTURAS (21) SE ENCUENTRAN ORIENTADAS DE TAL MODO QUE AL MENOS UNA DIMENSION ES PARALELA A UNA DIRECCION DE UN CAMPO DE POLARIZACION DE CC APLICADO.
