Obtain the Best Estimate of a Strongly Scattering Object from Limited Scattered Field Data

Introduction to Imaging from Scattered Fields presents an overview of the challenging problem of determining information about an object from measurements of the field scattered from that object. It covers widely used approaches to recover information about the objects and examines the assumptions made a priori about the object and the consequences of recovering object information from limited numbers of noisy measurements of the scattered fields.

The field of metamaterials arose from a deepened understanding of how electromagnetic waves interact with materials and subwavelength-scale scattering structures. The exploitation of these more-complex material-wave interactions has generated much global research activity. We can, in principle, engineer materials to greatly extend the selection of those currently available. This Tutorial Text presents the electromagnetic properties of both naturally occurring and manmade materials, focusing especially on structured or engineered metamaterials. After a review of Maxwell's equations and...
