Abstract: | This paper relates the scattering of a electromagnetic plane wave by a plane grating of conducting wires. The wires are parallel, equidistant and alternatively continuous and discontinuous. The discontinuous wires may be considered as dipole lines. The problem is numerically resolved. The conductor currents are determined by means of a system of first kind integral equations which is converted in a linear equations system by the moments method. The knowledge of currents permits the calculation of the reflection and transmission factors of the grating. Thus a matched state and a resonant state appear for discrete frequencies, where the transmission factor modulus is respectively 1 and 0. Experimentation on waveguide simulators gives a good agreement with numerical results. |
