This paper deals with the field on the surface of a dielectric slab covered by a periodically slotted conducting plane. The field is excited by a line of magnetic current. A sampling technique is used to formulate this problem. The field obtained by this method consists of a radiation field and contributions of surface and leaky waves. The beta-k diagram obtained by a sampling technique is compared with diagrams obtained by a variational method and experimentally. A graphical solution for the dispersion curve is presented. Surface waves that result from the solution in the improper Riemann surfaces are discussed. Author
