Abstract

We report on numerical calculations of the distribution of complex Fano parameters in a mesoscopic system consisting of a waveguide attached to a disordered cavity. An external magnetic field in the cavity breaks the time-reversal symmetry. The real and imaginary parts of the parameters as well as the widths are obtained by fitting the Beutler-Fano form to the calculated resonance data. The distributions are compared with the predictions from random matrix theory which have been modified to exclude resonances below a certain cut-off width.
