Abstract:
Statistical methods are practical and unavoidable in analysis of physical and engineering results. Study of anufacturing errors and uncertainties in construction of radio frequency structures is one of cases which statistical quantities is used. In this paper, we quantify uncertainty in the cutoff frequency of a waveguide using the chaos polynomial expansion method. Different distributions for uncertainty in the waveguide width are considered. We then investigate the effect of the distributions on the waveguide cutoff frequency. Using statistical quantities, we determine the amount of acceptable error during the construction of the waveguide such that it does not affect the wavequide performance.
