SYLLABUS/CONTENT

• Course organization, motivation and applications
• Introduction to guided propagation
• Maxwell's equations in form suited to study mode propagation
• Transverse components in terms of the axial components. Equations for the axial components
• Boundary conditions on perfect electric conductors and dielectric interfaces for the axial components
• TEM modes and consequences on voltages and currents
• Exercises on the calculation of TEM modes in guiding structures of interest
• Propagation of TE and TM modes in closed and homogeneous guiding structures
• Considerations about group, phase, signal velocities
• The effect of dielectric losses on the propagation of TE and TM modes in closed and homogeneous guiding structures
• Exercises related to the modes in rectagular waveguides
• Exercise: current on the wall of a WR in the presence of the fundamental mode. Slotted waveguides for measures and slot antennas
• Circular waveguides and related applications
• Modal vectors, voltages, currents and impedances. Fictitious transmission lines for determining the axial dependence of the modal fields in closed and homogeneous guiding structures
• Quasi-TEM modes for inhomogeneous transmission lines
• A few considerations on the modes of dielectric waveguides
• Mode completeness and its consequences
• Active power transmitted by modes through a cross-section
• A quick analysis of resonant cavities
• Effects of metal losses on mode propagation
• Approximate descriptions of linear passive components: matrices S, generalized S, Z, Y
• Common microwave components with one, two, three and four ports: simple loads, attenuators, phase shifters, insulators, overview on filters, directional couplers, circulators, hybrid junctions
• Common applications of components: phase shifters in simple antenna arrays; circulators as duplexers; attenuators, phase shifters, directional couplers and hybrid junctions in microwave measurements
