HighFrequency Electromagnetic Techniques: Recent Advances and ApplicationsHighFrequency Electromagnetic Techniques Electromagnetic engineers often deal with problems in which the surfaces of the geometrics being studied do not conform to the eleven coordinate systems in which wave equations are separable. In such cases, when exact solutions of wave equations don’t apply, approximate methods must suffice. Among these is the class of highfrequency analytical techniques covered in this book—methods which lately have proven themselves to be indispensable to the design and analysis of radar systems, antennas, the interpretation of results in remote sensing, and the assessment of electromagnetic compatibility and electromagnetic interference in computer circuits. The most comprehensive guide to the subject currently available, HighFrequency Electromagnetic Techniques provides an indepth look at the latest methods for highfrequency analysis. Designed to help professionals find fast, accurate solutions to their design and analysis problems, this valuable working resource features many case studies and realistic examples which vividly demonstrate exactly how highfrequency techniques can be applied to such areas as:
