Electromagnetic Field Theory

This lecture covers the fundamentals of the electromagnetic field theory, including the representation of the electromagnetic field using symbols, the system of MKSA or SI units, vector fields, and the physical interpretation of vector operators. It also delves into Maxwell's equations without sources, the relationship between permittivity, permeability, and the speed of light, and the concept of refractive index. The lecture further explores the response of the medium through the polarization term and the Lorentz model, which describes matter as a collection of harmonic oscillators. Additionally, it discusses the specific form of Maxwell's equations for a monochromatic plane wave.
