Description:With increasing operating frequencies of digital electronic devices, limitations are becoming evident in existing modeling techniques. Elsewhere in electromagnetics itself there are new modeling challenges with the introduction of integrated planar microwave circuits, as neither conductors nor dielectrics can be considered ideal at these very high frequencies. This book acts as a bridge between the mathematical abilities of the pure EM theorist and those of the FET circuit modeller; it combines the two fields by introducing analytical techniques encompassing the linear modeling of both passive and active structures, in particular FET structures. The resulting text will be of equal benefit to researchers in microwave and millimetric components and as an advanced textbook for specialized courses.Also available:Microwave Measurements, 3rd Edition - ISBN 9780863417351Geometrical Theory of Diffraction - ISBN 9780852968307The Institution of Engineering and Technology is one of the world's leading professional societies for the engineering and technology community.
