Synopsis:

The first part of Classical Electrodynamics building on Maxwell macroscopic theory: description of methods used in solutions of Maxwell equations in gradually more and more complex media (starting from homogeneous and isotropic, trough homogeneous and non-isotropic up to weakly non-homogeneous ones) concluded by scalar theory of diffraction.

Requirements:

Electricity and Magnetism (compulsory)

Waves, Optics, and Atomic Physics (recommended)

Syllabus of lectures:

1.Maxwell Macroscopic Theory - Recapitulation

2.Special Theory of Relativity Applied to Electromagnetic Theory

3.Concept of Plane Electromagnetic Waves (PEW)

4.Propagation of PEW in Homogeneous Isotropic Media (Wave Equation, Helmholtz Equation)

5.Poynting's Vector, Energy Flux and Conservation Laws

6.Polarisation of PEW (Stockes Parameters and Coherence Matrix)

7.Propagation of PEW in Dispersive Media - Dispersion Relation

8.Propagation of PEW in non-isotropic Media - Overview

9.Propagation of PEW in non-isotropic Media - Crystals, Magnetised Plasma and Ferrits

10.Propagation of Electromagnetic Waves in Weakly non-homogeneous Media

11.Eiconal Equation, Equation of Amplitude Transfer and Beam Equation

12.Scalar Theory of Diffraction - Kirchhoff's Integral, Green Function

13.Method of Angular Spectrum

14.Approximate Methods of Diffraction Field Computation - Fresnel Diffraction

15.Approximate Methods of Diffraction Field Computation - Fraunhoffer Diffraction

Syllabus of tutorials:

Excercises are used in the form of solving specific examples as required for illustration of acquired theoretical knowledge.

Study Objective:

Goal of this subject is to master methods of solving Maxwell Equations for propagation of electromagnetic waves in basic types of media: homogeneous and isotropic, homogeneous and non-isotropic, weakly non-homogeneous, and in media causing diffraction.
