| Popis: | The physical theory of diffraction (PTD) is presented for triangular cylinders with faces consisting of soft ( electric ) and hard ( magnetic ) sections. It is shown that the specular reflections from such cylinders can be canceled and shifted with appropriate combinations of the soft and hard sections. The residual scattered field in the specular directions is produced by the fringe waves diffracted at the edges and junctions between the soft and hard sections. Due to the energy conservation law, the wave field of the canceled specular beams is distributed over the increased sidelobes. It is shown that the forward scattering is the same for the hard, soft–hard, and black cylinders. |
