    "abstract": "We calculate the exact transmission coefficient of a quantum wire in the\npresence of a single point defect at the wire\u0027s cut-off frequencies. We show\nthat while the conductance pattern (i.e., the scattering) is strongly affected\nby the presence of the defect, the pattern is totally independent of the\ndefect\u0027s characteristics (i.e., the defect that caused the scattering cannot be\nidentified from that pattern).",
