1. Use vectors in Cartesian, polar and spherical space and apply the Gradient, Divergence and Curl operators. 2. Derive the fundamental equations of electrostatic theory. Apply GaussÆ law, PoissonÆs and LaplaceÆs equations to solve capacitance and resistance problems, 3. Derive the fundamental equations of magnetostatic theory and apply the Biot-Savart law and AmpereÆs circuital law to solve magnetic field and inductance problems. 4. Derive MaxwellÆs equations and the resulting wave equation for uniform plane time-varying electromagnetic waves. Determine the propagation coefficient of uniform plane time-varying electromagnetic waves in loss-free and lossy media. Derive PoyntingÆs theorem and apply it to determine the power in electromagnetic waves. 5. Derive the transmission line equations. Determine the driving point impedance of terminated transmission lines. Apply the Smith chart to impedance matching problems.

The module is based on 12 teaching weeks within the semester with two lecture hours and 1 tutorial/problem solving hour per week. Some tutorial sessions will involve students attempting to solve electromagnetic problems, with the help of the lecturer. Other tutorials will involve 'question and answer' sessions where the students can ask the lecture any detailed question on electromagnetic theory and problems. The written exam accounts for 100% of the module assessment, in which the students must attempt four out of five questions. Each question , except for the last, contains a section on theory and a problem. The last question is a problem only.

None.
