Microwave imaging--a technique used in sensing a givenscene by means of interrogating microwaves--has recentlyproven its usefulness in providing excellent diagnosticcapabilities in several areas, including civil and industrialengineering, nondestructive testing and evaluation, geophysicalprospecting, and biomedical engineering.
Microwave Imaging offers comprehensive descriptions ofthe most important techniques so far proposed for short-rangemicrowave imaging--including reconstruction procedures andimaging systems and apparatus--enabling the reader to usemicrowaves for diagnostic purposes in a wide range of applications.This hands-on resource features:
* A review of the electromagnetic inverse scattering problemformulation, written from an engineering perspective and withnotations
* The most effective reconstruction techniques based on diffractedwaves, including time- and frequency-domain methods, as well asdeterministic and stochastic space-domain procedures
* Currently proposed imaging apparatus, aimed at fast and accuratemeasurements of the scattered field data
* Insight on near field probes, microwave axial tomographs, andmicrowave cameras and scanners
* A discussion of practical applications with detaileddescriptions and discussions of several specific examples (e.g.,materials evaluation, crack detection, inspection of civil andindustrial structures, subsurface detection, and medicalapplications)
* A look at emerging techniques and future trends
Microwave Imaging is a practical resource for engineers,scientists, researchers, and professors in the fields of civil andindustrial engineering, nondestructive testing and evaluation,geophysical prospecting, and biomedical engineering.
