Assignment Brief -
Introduction - This assignment involves Computer Simulation and Visualisation with MATLAB of the Magnetic Field due to both a Conduction Current and Displacement Current, in an AC Driven Non-ideal Capacitor. The Capacitor consists of circular parallel plates with an imperfect dielectric between the plates. The detailed instructions on how to perform the simulation are given in the accompanying MATLAB-Based Electromagnetics manual. Carry out the instructions in the manual carefully (Programs ME6_11.m and ME6_13.m) with assistance from the tutor.
