Starting with the field of equations@ the book first outlines the theoretical basis for microwave circuit theory with particular emphasis on its similarity to@ and difference from@ the low frequency counterpart. This leads to an identification of parameters to be measured and is followed by a survey of measurement methods with the emphasis on the 'why' in addition to 'how'. Special emphasis is given to 'power equation method'@ adapter evaluation@ the six-port network analyser and noise. In these areas in particular@ the book includes recently developed material that has not been previously published. Author Glenn F. Engen
