Reviews

"... a powerful book that every scientist and engineer working in the area of biomedical applications of RF/microwave should read and keep for reference.... useful to a wider audience of engineers and medical specialists since the material is presented in a  concise way emphasizing core concepts and relevant examples. This is an excellent book; we need more like it." (IEEE Microwave Magazine, October 2006) "…a well-researched document and a useful addition in the library for advanced RF/Microwave Engineering courses in universities, research labs working in this area as well as technologists having an interest in this field." (Desicritics.org, July 4, 2006) "...a reference to the medical physicist on a subject that is undergoing a great deal of development at this time and...a teaching reference in a course on nonionizing radiations." (Health Physics, June 2006)
