Abstract

Consider a plane wave incident on a conducting strip of infinite length coated on one side with a thin, uniform coating of lossless dielectric, and let the incident magnetic field vector be parallel to the edges of the strip. From first principles we develop the integral equations relating the total, incident, and scattered fields in the dielectric. We expand the fields in the dielectric slab as the sum of three plane waves (the 'forced' wave and two oppositely-directed surface waves). The phase constants in the x and y directions are known and the wave amplitudes are found using least-squared- error-point-matching. The far-zone scattered field is found by letting the polarization and conduction currents radiate in free space. Data are presented showing the bistatic scattering characteristics of the dielectric-coated conducting strip as a function of dielectric permittivity, slab width and thickness, and angle of incidence. Results show reasonable agreement with conventional moment method solution using pulse bases and Galerkin testing functions.
