Good Toolbox, I have used dslab.m and dguide.m files which are related to (TE modes in dielectric slab waveguide- TE-mode cutoff wavenumbers in a dielectric slab ), I wanted to reproduce that for TM modes, could you please help me how can I change that for TM modes?
With regard to file chebarray. It is my understanding that the central element excitation will always be the largest with odd number of elements. Your program doesn't show this when element size becomes > 11. Could you provide an explanation?
