This report concentrates mainly on the use of microwave sensors in the control of industrial processes and in the medical field. It reviews the current applications and future potential of microwave imaging with particular emphasis on near-field systems. It also describes the theoretical techniques and algorithms which are available for the generation of images from raw experimental data.

The goal of this work is the introduction of efficient antenna structures on the basis of the requirement of different microwave imaging methods; i.e. quantitative and qualitative microwave imaging techniques. Several criteria are proposed for the evaluation of single element antenna structures for application in microwave imaging systems. The performance of the proposed antennas are evaluated in simulation and measurement scenarios.

Handbook of Microwave and Optical Components Editor-in-Chief: Kai Chang This important, four-volume work covers recent developments in a field that continues to evolve at an extraordinarily rapid pace. The information given is almost entirely of a practical nature, with theoretical discussions and mathematical formulations given only where essential. Consequently, the Handbook is the definitive source guide for professionals working in optical and microwave engineering. It covers all important areas of microwave, millimeter-wave, submillimeter-wave, infrared, and optical frequency spectra—from essential principles, methods, design information, and references for solving all types of problems in high-frequency spectra.

Robinson This interdisciplinary journal offers comprehensive coverage of the theory and applications of imaging technology. Papers are drawn from a wide range of areas—holography, optical processing, engineering, chemistry, radiology, geology, geography, astronomy, computer and materials science, and mathematics. The journal provides a single source for current information pertinent to engineers and specialists working in imaging technology, as well as a forum for the development of new technology.

Microwave imaging techniques allow for the development of systems that are able to inspect, identify, and characterize in a noninvasive fashion under different scenarios, ranging from biomedical to subsurface diagnostics as well as from surveillance and security applications to nondestructive evaluation. Such great opportunities, though, are actually severely limited by difficulties arising from the solution of the underlying inverse scattering problem. As a result, ongoing research efforts in this area are devoted to developing inversion strategies and experimental apparatus so that they are as reliable and accurate as possible with respect to reconstruction capabilities and resolution performance, respectively. The intent of this Special Issue is to present the experiences of leading scientists in the electromagnetic inverse scattering community, as well as to serve as an assessment tool for people who are new to the area of microwave imaging and electromagnetic inverse scattering problems.
