Course Description: ECE 458 is a follow-on course to ECE 350 concerned with the complexities of EM wave propagation on and around our planet with a special focus on near-Earth space environment including the troposphere, stratosphere, mesosphere, ionosphere, magnetosphere, and solar wind, the last three occupied by magnetized plasmas. We will assume ECE 350 level familiarity with Maxwell's equations, antenna fundamentals, and plane wave concepts, as well as familiarity with linear system theory tools (ECE 210) and random signals and thermal noise (ECE 313, ECE 350). Very broadly, the first one third of the course is focused on radiowave communications links near the ground and within the troposphere, the middle third on ionospheric propagation above 50 km altitude and sky-wave communication links, and the last third on radio remote sensing of the near Earth space environment using reflective and scattering based techniques.
