Abstract
The spectra of forward an backward travelling parasitic modes generated by plane and curved, phase correcting mirrors in highly overmoded HE11 and TE01 corner bends (90°) have been measured using a wavenumber spectrometer (f = 70 GHz, I.D. = 27.79 mm, ka = 20.39). The experimental spectral distributions and the measured power levels in transmitted and reflected undesired spurious modes are in good agreement with theoretical predictions.
