Identification of Suspicious Mass in Biological Tissues Using Resonance Parameters Extracted from Late Time Response

Singularity expansion method (SEM) has been used for a long time to directly extract residues and poles of a target from its transient response. It is well known that the complex natural resonances (CNRs) extracted from the transient response are aspect independent, while they are only function in the geometry and electrical properties of the target. In this paper, a new approach applying generalized pencil of function method (GPOF) has been presented for detection and characterization of suspicious mass in biological tissues.
