dc.description.abstractEste artículo analiza la efectividad de apantallamiento electromagnético de varias estructuras de concreto en función de la variación del grosor y el contenido o nivel de humedad (NH), para un rango de frecuencias definido. El estudio se fundamenta en la implementación de simulaciones en dos dimensiones (2D) usando un software basado en el método de elementos finitos (FEM) y se desarrolló a partir de un conjunto de valores obtenidos de la aplicación de modelos matemáticos para medios dieléctricos. Inicialmente, se caracterizan las propiedades eléctricas complejas (permitividad dieléctrica y conductividad) de las estructuras aplicando el modelo matemático de Jonscher de tres variables. Posteriormente, se evalúan dichas propiedades en un rango de frecuencias determinado. Como resultado, se observa que el blindaje electromagnético ofrecido por el concreto aumenta cuando se incrementa el NH y el grosor de las estructuras. Adicionalmente, las pruebas evidencian que las pérdidas de energía por absorción son mayores en comparación con los demás tipos de pérdidas analizadas en el estudio.spa
dc.description.abstract   This article analyzes the effectiveness of electromagnetic shielding of several concrete structures based on the variation of the thickness and the content or humidity level (NH), for a defined frequency range. The study is based on the implementation of simulations in two dimensions (2D) using a software based on the finite element method (FEM) and was developed from a set of values obtained from the application of mathematical models for dielectric media. Initially, the complex electrical properties (dielectric permittivity and conductivity) of the structures are characterized by applying the Jonscher mathematical model of three variables. Subsequently, these properties are evaluated in a specific frequency range. As a result, it is observed that the electromagnetic shielding offered by the concrete increases when the NH and the thickness of the structures are increased. Additionally, the evidence shows that energy losses due to absorption are greater compared to the other types of losses analyzed in the study eng
