Topics include the design of filters in high frequency applications, the nature and selection of dielectric materials, measurement of permeability and permittivity, the design of tapers and filters themselves, the cascading of lossy and reactive filters, integrated filters, balanced transmission filters, high power and HF lossy filters, filters with dielectric loading and static magnetic fields (magnets). Note that this book was revised from a monograph in the previous Electronic Engineering series written by engineers at the Georgia Institute of Technology.
