Based on two inequalities, it is presented that the cut-off wave number of the ( ) lowest order transverse magnetic TM mode of a hollow metallic waveguide of arbitrary cross-section is a function of the area, the perimeter and the inscribed circle radius. The results obtained by the derived formulas
