The perfectly matched layer (PML) absorbing boundary condition has been used for a wide range of applications since its introduction in 1994. Most of these applications have used the PML in a uniform air‐filled zone around a nonair scatterer. This paper describes the application of the PML to a geophysical prospecting problem where the PML is applied in a conductive host material containing the scatterer. The conductivity profile is optimized using parameter estimation. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 25: 253–255, 2000.
