The model for the edge-coupled microstrip line is now complete, and in related news the 2D Finite Difference code for generic edge coupled lines is also completed.  I'd treat the 2D Finite Difference code as beta for now, it seems to check out but has not been rigorously tested.  Both of these are described in the microstrip section of the documentation.

I've working on my first draft of my Mason workbook.  The workbook is written as a series of labs geared for supplementing a high school or physics level physics or engineering class.  It would also be appropriate for those who have a basic understanding of RF and want the step-by-step tutorials for using Mason.
