✦ Synopsis
An efficient technique to locate minima zeros in the smallest singular ¨alue of a singular ¨alue decomposition, as used to sol¨e eigen¨alue problems in electromagnetics, is presented. The efficiency of the technique depends only on the a¨ailability of a sufficiently accurate representation of the smallest singular ¨alue; the sharpness of the peaks is of minor rele¨ance. The technique is applied to determine the cutoff wa¨e numbers of a ridge circular wa¨eguide to demonstrate its efficiency.
