Abstract
A method for determining a parameter of a material of interest which includes: directing, using a radio frequency (RF) source, RF energy into a region of interest, the region of interest comprising the material, a known reference and a boundary between the material and the known reference; detecting, using an acoustic receiver, at least one thermoacoustic multi-polar signal generated in response to the RF energy; and determining, by the one or more processors, a parameter of the material as a function of the at least one thermoacoustic multi-polar signal and a transmitted power correction factor, wherein the transmitted power correction factor is based on an estimated thickness of the known reference and an attenuation coefficient of the known reference.
