dc.description.abstractThis work presents the development of electromagnetic model for the laboratory 2-D Soil-Bed setup, which was developed at the Civil Engineering Department of the University of Puerto Rico, Mayaguez, to verify the posibility to detect a contaminant (DNAPL) in the subsurface, using Cross Well Radar (CWR) technologies. The electromagnetic model developed using two electromagnetic simulators, Ansoft’s HFSS and Remcom’s XFDTD. The simulations are done for dry and saturated sand, with and without the contaminant, with different shapes and positions of the contaminant pools within the tank, transmitting through all the different ports independently, where we observed for each case the E-field propagation and S-parameters at the three analysis frequencies of 285 MHz, 515 MHz and 1.5 GHz. The results of the XFDTD simulator are used to verify the results in the HFSS simulator. The analysis of the S-parameters, taking into account the position of the ports, shows it is possible to detect the contaminant in dry sand and saturated sand at the analysis frequencies.en_US
dc.description.abstractEste trabajo presenta el desarrollo del modelo electromagnético computacional de un tanque de flujo en dos dimensiones, el cual fue desarrollado en Ingeniería Civil de la Universidad de Puerto Rico, para verificar la posible detección en el subsuelo de un contaminante (DNAPL), usando tecnología CWR. El modelo fue desarrollado usando dos simuladores electromagnéticos Ansoft’s HFSS y Remcom’s XFDTD. Las simulaciones son hechas para arena seca y húmeda, con y sin contaminante, con diferentes formas y posiciones del contaminante dentro del tanque, transmitiendo a través de todos los puertos independientemente, donde nosotros observamos para cada caso la propagación del campo eléctrico y los parámetros S a las tres frecuencias de análisis 285 MHz, 515 MHz y 1.5 GHz. Los resultados del simulador XFDTD son usados para verificar los resultados del simulador HFSS. El análisis de los parámetros S, tomando en cuenta la posición de los puertos muestra detección del contaminante en arena seca y saturada a las frecuencias de analisis.en_US
