(PDF) GprMax - A Finite-Difference Time-Domain Electromagnetic Simulator

(PDF) GprMax - A Finite-Difference Time-Domain Electromagnetic Simulator Abstract gprmax (http://www.gprmax.com) was originally developed in 1996 when electromagnetic numerical modelling using the fdtd method was in its infancy. It solves maxwell's equations in 3d using the finite difference time domain (fdtd) method. gprmax was designed for modelling ground penetrating radar (gpr) but can also be used to model electromagnetic wave propagation for many other applications.

(PDF) Finite-Difference Time-Domain 1D, 2D, And 3D Simulation Of ... The time domain nature of the fdtd method means in a single simulation a wide range of frequencies can be modelled. this is particularly well suited for simulating gpr systems which are usually ultra wide band (uwb). We will be giving a pre conference workshop on 23 june 2024 with sessions on the underpinning theory and finite difference time domain (fdtd) method, as well as hands on demonstration and examples using gprmax. Tl;dr: gprmax is open source software that simulates electromagnetic wave propagation, using the finite difference time domain (fdtd) method, for the numerical modelling of ground penetrating radar (gpr). Since then a number of commercial and other freely available fdtd based solvers have become available, but over the past 18 years gprmax has been one of the most widely used simulation tools in the gpr community.

Estimating the diameter of rebars using gpr is particularly challenging with no conclusive solution. using a synthetic training set, generated using gprmax, we managed to effectively train ml schemes capable of estimating the diameter of rebar in an accurate and efficient manner [6], [7].
