Abstract
A simple numerical procedure for finding the loci of TE and TM leaky wave poles as the frequency or the thickness of the slab varies is presented. These loci provide important information when the integration path of the Sommerfeld integral for the grounded dielectric slab problem is deformed into the improper sheet of the Riemann surface. The accuracy of the loci has been checked extensively against contour plots of separate expressions for the electric flux density for the TE and TM cases.<>
