✦ Synopsis

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 ha¨e 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 conducti¨e host material containing the scatterer. The conducti¨ity profile is optimized using parameter estimation.
