ABOUT THE COURSE: The course begins with an introduction to microwave networks. Thereafter, it investigates the basic and general relationships of modal orthogonality in cylindrical guides of arbitrary cross-section. Field expressions and propagation behavior inside such guides are also investigated. Next, the obstacle problem in the waveguide is treated. This is followed by the analysis and network modeling of two waveguide discontinuities : the post and the diaphragm. Thereafter, the waveguide junction problem is investigated with reference to the capacitive and inductive waveguide junctions. The numerical modeling of the waveguide feed is next investigated, with reference to a probe feed in a waveguide. The circuit modeling of apertures excited through waveguides is addressed. Modeling of cavities is undertaken, alongwith determination of the input impedance of a probe-excited cavity and the problem of a waveguide aperture-coupled to a cavity. Treatment of apertures in ground-planes is addressed. Modeling of radiation from a plane current sheet is investigated. Finally, cylindrical waves and their treatment are examined.
