Comparison of Different Absorbing Boundary Conditions for GPR Simulation by the Time Domain Finite Element Method
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 3
Abstract
This paper compares three boundary conditions, i.e. transmitting boundary condition, Sarma absorbing boundary condition and the uniaxial complete matched layerabsorbing boundary condition for simulation of ground penetrating radar (GPR) by the time domain finite element (FEM) method. The formulations of the three boundary conditions for the FEM method are described. Their effectiveness in absorbing the incident electromagnetic waves are evaluated by the reflection coefficient on the boundary of a simple GPR model.The results demonstrate that UPML boundary condition can yield a reflection coefficient smaller than -50 dB, which is -20 dB smaller than other two boundary conditions.
