Solution of Maxwell's Equations for the Simulation and Optimization of the Radar Assessment of Concrete Structures

Recent developments in ground-penetrating radar (GPR) models have brought about complex electromagnetic fields due to the fine variations of structures. Therefore, it has become necessary to use more accurate analysis including environmental characteristics, antennas, and interpretation of the raw data in three-dimensional space. Such analyses require numerical techniques by which problems having complex scattering properties can be solved as accurately and as fast as possible. Some methods had been developed for resolution of specific problems involving differential or integral equations. However, each technique has limitations and trade-offs. The research work presented in this article aims to develop electromagnetic wave-propagation models in concrete structures using different numerical techniques to investigate the detection and location of buried objects.
