Abstract

Diffraction of an incident plane wave caused by a perfectly conducting, infinitesimally thick half-plane is considered in the far-field region for the case when the electric vector is polarized perpendicular to the axis of the edge. Measurements in all quadrants, with microwaves and a 0.059λ-thick screen, verify the theoretical solution of the problem due to Sommerfeld. A pronounced thickness effect is observed in the irradiance distribution when 0.18λ- and 0.37λ-thick planes are examined. The dependence with respect to polarization of the thickness effect in the diffraction pattern is discussed.
