Guided Propagation: Modes and Wave Impedance

This lecture covers the guided propagation of electromagnetic waves in different structures such as coaxial cables, optical fibers, and waveguides. It explains the TEM mode and the characteristic equations to solve Maxwell's equations. The lecture also delves into the concept of wave impedance and the longitudinal propagation factor in TEM and TM modes. Dispersion and distortion effects in dispersive propagation lines are discussed, along with the Fourier transform of a Gaussian pulse. The guided wavelength, group velocity, and phase velocity in guided propagation are explored, emphasizing the importance of understanding wave behavior in different mediums.
