Introduces the basics of wave propagation, covering longitudinal and transverse waves, superposition, reflection, d'Alembert equation, Fourier decomposition, and wave surfaces.
Explores the photon concept in electromagnetic waves, including energy, momentum, emission by charges, coherence length, and the electromagnetic spectrum.
Covers the coupling of waves in periodic structures, focusing on the reflection coefficient for one period and the limitations of the Coupling of Modes approach.
