Authors/developers

The original version of gprMax was created in 1996 by Professor Antonis Giannopoulos. In 2015 Dr Craig Warren re-developed gprMax from scratch, which gave birth to the software in its current state. Both Antonis and Craig continue to work on, and supervise, ongoing developments to gprMax.

Additionally, the following people have contributed code, research, and ideas to the development of gprMax:

Consultancy & training services

We are able to offer consultancy services and expert advice on GPR, and in particular the numerical modelling of GPR, for a wide range of different applications.

We also offer training workshops on the numerical modelling of GPR using gprMax. Our workshops are interactive and will typically include sessions on:

• background and theory of the Finite-Difference Time-Domain (FDTD) method;
• an overview of gprMax, covering basic and more advanced features;
• installing gprMax and running your first simulation;
• detailed examples of different GPR simulations including: antenna modelling, soil mixing models, and dispersive materials;
• how gprMax can be used for modelling other EM applications.

We can also tailor our workshops towards your specific modelling requirements.

If you are interested please get in touch by contacting either Professor Antonis Giannopoulos or Dr Craig Warren to discuss your requirements.
