Main function is 'h_plane_bpf.m' with parameters explained at the beginning.
The code generates all required dimensions of filter structure as well as X,Y points suitable for importing in CST or other sofware for further verification.
Give the sythesis step some time.
Comparison of simulation results obtained by this code and CST Frequency domain solver is shown in following pictures. To obtain a good match, sufficiently tight adaptive meshing settings must be used in CST, thereby it takes some time to calculate. In case of this code, it takes only a few seconds due to analytic mode matching method.
Tested only with MATLAB 2015a.

*greatly improved synthesis speed by implementing use of fminbnd()
*added option so synthesize filters with rounded corners for better manufacturability. See parameter 'r_fillet'.
*fixed a few bugs in MM solver code
