Abstract :
The 2D problem of the stepped mitered waveguide bend is considered for both E and H polarizations of incident waves. The method used for analysis is the mode-matching technique (MMT). Geometric parameters of such a device that can provide a low level of return loss within the whole operating frequency band are found for WR90. It is proved that even 4 steps are enough to match the device to better than -30 dB.
