Abstract
Accurate two-dimensional mathematical model of the scattering of the natural electric-type guided modes of a slab dielectric waveguide from the finite number of rectangular grooves cut in the perfectly electric conducting (PEC) screen is built. A narrow beam with sidelobe level 2OdB is optimized with the aid of genetic algorithm. Application to leaky-wave antennas is discussed.
