“…In Reflex-Win software, modeling results are obtained using the finite difference time domain (FDTD) method. The FDTD technique has been widely used to analyze EM phenomena (Tirkas & Demarest, 1991;Jurgens et al, 1992;Luebbers, Steich, & Kunz, 1993;Huang, 1996;Chen & Huang, 1998;Bergmann, Robertsson, & Holliger, 1998;Oguz & Gurel, 2001). This technique is used for accurate modeling near field time-domain GPR and it can also model antennas and targets with complex shapes with virtually no additional computational effort (Roberts & Daniels, 1997).…”

The Aydintepe underground settlement in northeastern Turkey is a series of subsurface galleries carved in Eocene-aged volcanic tuff. Rescue excavations conducted by the Local Archaeological Museum of Erzurum in 1996 and 1997 uncovered a large settlement with several underground rooms linked by passages. According to the excavators, it may have been built as a hideout and shelter by the first Christians who were banished by the Romans during the 3rd century A.D. Despite its historical and touristic value, parts of the underground settlement at Aydintepe have been destroyed to make room for the construction of new buildings in the modern town. As part of a conservation strategy for this important archaeological resource, a series of ground penetrating radar (GPR) and electrical resistivity measurements were conducted along eight profiles between 2003 and 2005. GPR soundings with a 100-MHz unshielded antenna yielded reflected hyperbolic signals with high amplitude from tunnel structures. These highamplitude signals corresponded to areas of high electrical resistivity. These anomalies allow us to determine the probable locations of tunnels within the underground settlement and they provide important data that can be used to prevent future damage from modern construction.

A method for ground-penetrating radar amplitude recovery of targets is presented in this paper. We use the migration processing for target imaging and the clean method to extract featured target points.Based on the featured target points, target reflection hyperbolas are calculated. Curve fitting is applied to get amplitude attenuation parameters. The amplitude is recovered after compensating the parameters to the raw data. We performed a field experiment with 5 sphere targets under water. Comparing to the conventional methods, our proposed method is more effective for target classification.

“…[22], mas só recentemente vem se tornando um dos métodos numéricos mais explorados no eletromagnetismo computacional, devido a sua precisão numérica, bom desempenho computacional quanto ao uso de processamento e vasto número de aplicações [14]. Para exemplificar o FDTD-2D tem sido aplicado em análises de efeitos biológicos [23], [24], antenas [25], [26], radar [27] e em dispositivos optoelectrônicos [28].…”

This work presents the integration of different computational techniques to specify and design a new computational electromagnetic simulator, called Free Visual FDTD 2D (FV-FDTD-2D), to support the Telecommunications teaching-learning process. Some Software Engineering, humancomputer interface (HCI) and an advanced numerical method, based on Finite Difference Time Domain (FDTD), were successfully integrated. It provides an efficient processing and usable software, which detailed documents for developers and comprehensive graphical output results. The FV-FDTD-2D has been adopted in some technical lectures related to telecommunications, presenting successful evaluations by the attempted public.
