This Matlab code with the finite element method based Partial Differential Equation Toolbox calculates and simulates the electromagnetic field, when a scatterer (copper) object is cloaked with transformation optics designed metamaterial. This electromagnetic cloaking effect can be studied and demonstrated with this program. The code includes two source type (finite length line source and point source), and two sets of metamaterial parameters (exact and reduced metamaterial parameters). You can choose from them arbitrarily. Additionally an Animation.m file is attached, which can animate one period of the wave propagation in steady-state.

Required Products Partial Differential Equation Toolbox
MATLAB release MATLAB 7.10 (R2010a)
MATLAB Search Path
Other requirements In default the code uses 4x refinement (approx. 250000 triangles in the mesh). For computers with lower performance less refinement is recommended.
