Abstract

SE PRESENTA UN FILTRO POLARIZADOR PARA SUMINISTRAR UNA SEÑAL DE SALIDA SO QUE CONTENGA SOLAMENTE UNA (TE O TM) DE LAS DOS POLARIZACIONES (TE Y TM) EN UNA SEÑAL DE ENTRADA SI, EL FILTRO COMPRENDE UNA SECCION INTERMEDIA DE GUIA (5) ENTRE UNA SECCION DE ENTRADA (A) Y UNA SECCION DE SALIDA (B). LA SECCION DE SALIDA ES UN BIFURCADOR DE MODO QUE TIENE UN CANAL DE SALIDA MONOMODAL (3) PARA LA SEÑAL DE SALIDA SO Y UN CANAL INACTIVO MONOMODAL (4) QUE SE DESVIA MAS ALLA DE LA DISTANCIA DE INTERACCION (D). EL CANAL DE SALIDA (3) TIENE UNA CONSTANTE DE PROPAGACION INFERIOR A LA DEL CANAL INACTIVO (4). LA SECCION DE ENTRADA (A) QUE TIENE UN CANAL DE ENTRADA (1) Y UN CANAL INACTIVO (2) ES UN BIFURCADOR DE MODO INVERSO QUE PUEDE SER LA IMAGEN A ESPECULAR DE LA SECCION DE SALIDA (B). LA SECCION DE GUIA (5) ES MONOMODAL PARA UNA DE LAS DOS POLARIZACIONES Y BIMODAL PARA LA OTRA POLARIZACION. AMBAS POLARIZACIONES DE LA SEÑAL DE ENTRADA SI QUE PENETRAN POR MEDIO DEL CANAL DE ENTRADA (1) SE CONVIERTEN INICIALMENTE EN MODOS DE PRIMER ORDEN, DE LOS CUALES SOLAMENTE UNO ES UN MODO GUIADO DE ESA SECCION CONDUCTORA Y ALCANZA LA SEÑAL DE SALIDA, EN DONDE SE PROPAGA, ADEMAS, A LO LARGO DEL CANAL QUE TIENE LA CONSTANTE DE PROPAGACION MAS BAJA. EL MODO DE PRIMER ORDEN DE LA OTRA POLARIZACION SE PIERDE.
