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
