Abstract : A computational technique has been developed to calculate the electromagnetic scattering from two-dimensional wing profiles loaded by impedance strips. These strips are represented by impedance boundary conditions. This report deals with the parallel electric polarization (TM polarization) while a similar study of the perpendicular polarization is contained in Reference (1). The effect of the impedance loading is studied for different shapes and sizes of the wing, and for different angles of incidence. The last part of the report deals with the relation between two- and three-dimensional scattering. Three-dimensional problems may in certain cases be solved at least approximately from the knowledge of the scattered field in two-dimensional problems. (Author)
