Electromagnetic Fields and Waves I

Students will be able to: 1. state and explain the various electromagnetic laws; 2. derive and explain Maxwell’s equation in rectangular coordinates; and 3. explain wave propagation mechanism in conductors and unbounded dielectric media.

Review of electromagnetic laws in integral form, Gauss’s Law, Ampere’s and Faraday’s Laws. Electrostatic fields due to distribution of charge. Magnetic fields in and around current carrying conductors. Time-varying magnetic and electric fields. Conduction and displacement current. Maxwell’s equations (in rectangular co-ordinates and vector-calculus notation). Derivation of Maxwell’s equations, electromagnetic potential and waves. Poynting vector, boundary conditions. Wave propagation in good conductors, skin effect; plane waves in unbounded dielectric media.
