Abstract

EL APARATO MICROONDAS SE CARACTERIZA, PORQUE CERCA DE LA ABERTURA DE ACOPLAMIENTO (4) DEL CONDUCTOR HUECO (2) TAPADO POR MATERIAL QUE PERMITE EL PASO DE LAS MICROONDAS Y QUE COMIENZA EN UNA TERMINACION DEL CONDUCTOR HUECO Y POR LO MENOS ES X/2 LA LONGITUD DE ONDA DE LAS MICROONDAS SE ENCUENTRA EN EL CENTRO. LA POSICION DE SALIDA SE COLOCA EL PALPADOR DE CAMPO (3) EN QUE E = Y/O H = PLANO CON BRAZOS METALICOS Y EN COMBINACION CON ELLO, LA ALTURA ES POR LO MENOS 2 LAMBDAS Y LA ANCHURA Y LA PROFUNDIDAS ES 3 LAMBDAS DE LA LONGITUD DE ONDA DE LAS MICROONDAS SIENDO EL ESPACIO (5) DESDE EL PUNTO DE VISTA DE LA ABERTURA DE ACOPLADO DE MICROONDAS (4) SIMETRICA. DIRECTAMENTE DEBAJO DE LA ABERTURA (4) CERCA DEL CAMPO DE LAS MICROONDAS NO SE COLOCAN CONSTRUCCIONES METALICAS.THE MICROWAVE DEVICE IS CHARACTERIZED, BECAUSE NEAR THE COUPLING OPENING (4) OF THE HOLLOW CONDUCTOR (2) COVERED BY MATERIAL THAT ALLOWS THE PASSAGE OF THE MICROWAVE AND THAT BEGINS AT A TERMINATION OF THE HOLLOW CONDUCTOR AND AT LEAST IS X / 2 THE MICROWAVE WAVE LENGTH IS IN THE CENTER. THE EXIT POSITION IS PLACED THE FIELD PROBE (3) IN WHICH E = Y / OH = PLANE WITH METAL ARMS AND IN COMBINATION WITH IT, THE HEIGHT IS AT LEAST 2 LAMBDAS AND THE WIDTH AND DEPTH IS 3 LAMBDAS OF THE WAVE LENGTH OF THE MICROWAVES BEING THE SPACE (5) FROM THE POINT OF VIEW OF THE MICROWAVE COUPLING OPENING (4) SYMMETRICAL. DIRECTLY BELOW THE OPENING (4) NEAR THE MICROWAVE FIELD, NO METAL CONSTRUCTIONS ARE PLACED.
