Some authors start their design from cutoff frequency. (DFW/SIW slotted arrays). So waveguide has width a little wider to obtain cutoff frequency a little lower than slot resonating frequency. But i have many concerns. If waveguide is narrow, then guided length may be larger than free space wavelength.
My idea: maybe it is good idea to choose such waveguide width which will give guided wavelength the same as free-space wavelength?
