this is a new multi grid approach for the cylindrical FDTD. The FDTD domain will be split in two regions in radial direction. The "inner" region will have half as many disc-lines in alpha direction and therefore allow for a much larger timestep which increases the simulation speed. Todo: - currently only a homogeneous disc is allowed in alpha direction - some extensions have to be tested and prepared for this approach (e.g. pml) - speed enhancement and more efficient memory usage - lots and lots of testing...
