Course Objectives - As part of this course, students:

  1. develop an understanding of the fundamental concepts associated with electromagnetic fields and the guiding and radiation of electromagnetic waves
  2. apply basic electromagnetic concepts to the design of microwave circuits, resonators, and antenna systems [a,c,k]
Course Outcomes - Upon successful completion of this course, students should be able to:

  1. understand meaning and use of fundamental transmission line concepts: traveling and standing waves, wavelength, characteristic impedance, attenuation.
  2. design common transmission lines (coaxial, microstrip, stripline) to achieve a given characteristic impedance.
  3. understand the Smith chart (generalized reflection coefficient plane) and its use for fundamental transmission line calculations.
  4. design simple matching networks using lumped elements, quarter-wave sections, and stub tuners.
  5. understand basic principles associated with waveguide: modes (TEM, TE, TEM), cutoff frequency, guide wavelength, velocities.
  6. understand the concept of resonance and quality factor (Q) for lumped element circuits, transmission line sections, and metallic cavities.
  7. be familiar with the scattering matrix representation for microwave devices and the special properties that result for lossless and reciprocal devices
  8. understand the operation of simple power dividers and 4-port hybrids.
  9. design low pass, band pass, and high pass filters using the insertion loss method.
  10. understand the basic concepts associated with antenna performance, such as, field pattern, directivity, beamwidth, gain, radiation resistance.
  11. understand the relationship between transmission and reception for a single antenna and link calculations for two antennas (Friis formula).
