Method of Including Full-Wave Source Model in Acoustic and Electromagnetic Scattering and Inverse Scattering Formulations
4844 – In this disclosure we describe a technique for imbedding a full-wave source model in the traditional integral equation formulations of acoustic and electromagnetic scattering and inverse scattering. This method directly links the material properties of the scatterers to measurement quantities. Traditionally, we model the physics of wave scattering due to inhomogeneous objects with a surface...

Antenna and Propagation Model for Free-space Measurements and Experimental Inverse Scattering
4752 – The purpose of this procedure is to model the full-wave response of an antenna for use in two-way propagation models and experimental inverse scattering. We have developed a model for our antennas which provides the incident field on transmit (the field produced in the absence of objects) and the measured voltage on receive (an angle-dependent coherent sum of all incoming fields), and can...

Method for Large-Domain Microwave Breast Imaging
4751 – Microwave inverse scattering algorithms form maps of the dielectric properties of objects. The dielectric properties of objects consist of the permittivity and conductivity. Images are formed through an optimization procedure that compares the electric fields scattered off an object in experiment to the electric fields predicted by a numeric forward model and object. If the numeric forward... Read More
