Abstract
UNA ESTRUCTURA DE MULTIPLES CAPAS UTILIZA DOS CAPAS COMPLEMENTARIAS DE IMPEDANCIA (4,6) Y UNA PIEZA BASE (2) PARA OFRECER UNA CARACTERISTICA DE TRANSMISION OPTICA PARA LA ESTRUCTURA DE CAPAS COMPLEMENTARIAS DE IMPEDANCIA DOBLE. LA ESTRUCTURA DE MULTIPLES CAPAS POSIBILITA UNA OPTIMA TRANSMISION DE UNA SEÑAL ELECTROMAGNETICA (10) PARA AMPLIOS ANGULOS DE INCIDENCIA Y PRESENTA UNA SENSIBILIDAD MINIMA A LA POLARIZACION DE LA SEÑAL.
