heal.abstract	A very efficient, simple, and rapidly convergent algorithm for solving the Carleman-type singular integral and integro-differential equations formulating a variety of problems related to scattering by strips and slots in the presence of a dielectric half-space is presented. The method, based on Neumann's expansion of the Hankel-function kernel of the integral equations, is particularly suited to the case of wide strips or slots where well-known problems of decimal cancellation and slow convergence are now completely avoided. The algorithm can easily be extended to the case of strips inside or on the surface of dielectric slabs. Numerical comparisons with classical results of scattering by very wide strips in free space, and under all possible angles of incidence, bring to light the power, simplicity, and accuracy of the new algorithm.	en
