Propagation and Antennas: Atmospheric Effects and Wireless Links

This lecture covers the absorption, diffusion, and refraction of electromagnetic waves due to rain, fog, and radiation. It also explores the propagation in inhomogeneous mediums, the impact of obstacles on wave propagation, and the concept of path loss in wireless transmissions. The instructor discusses antenna characteristics, noise in wireless systems, and the concept of Equivalent Isotropically Radiated Power (EIRP). The lecture delves into the assessment of wireless links, attenuation in propagation, and the power balance in wireless systems. It concludes with the analysis of signal-to-noise ratio in digital and analog transmissions.
