 Upon successful completion of this course it is intended that a student will be able to: 1)State the integral laws of electromagnetism and state and derive Maxwell's equations for charges and currents in a vacuum 2)Define and explain charge and current densities (in bulk and on surfaces and lines), and conductivity 3)Define, and use the concepts of electric and magnetic dipoles; calculate the fields from dipoles and forces and torques on them 4)Define and explain: polarisation and magnetisation; the fields D, H, E and B; the relation between E, B and the force on a particle; polarisation charges and magnetisation currents; boundary conditions on fields at interfaces between media; Maxwell's equations in media 5)Define and explain in atomic terms: the response of linear media; relative permittivity and permeability; their relation to the electromagnetic energy density; nonlinear media such as ferromagnets 6)Formulate and solve boundary-value problems using: superposition methods; uniqueness principles; the method of images; qualitative reasoning based on field lines; the equations of Biot-Savart, Faraday, Ampere, Gauss, Laplace and Poisson 7)Formulate and solve with vector calculus problems of static and time-varying electrical and magnetic fields 8)Derive and apply the concepts of: Maxwell's displacement current; the continuity equation; self- and mutual inductance; Poynting's vector; energy flux; radiation pressure 9)Derive and explain electromagnetic radiation using plane-wave solutions of Maxwell's equations; apply these to problems of intrinsic impedance, attenuation, dispersion, reflection, transmission, evanescence, and the skin effect in conductors; derive and explain total internal reflection, polarisation by reflection. 10)Explain and utilise the properties of the electric scalar potential and the magnetic vector potential.
