    Abstract

    In this work the scattering of plane waves from a finite sized perfectly conducting wedge as a function of its opening angle and the width of its faces is studied using the combination of physical optics (po) and the physical theory of diffraction (ptd). To find out under which circumstances the ptd contribution is significant compared to the PO, the ratio of the ptd field and the po field is evaluated as a maximum and a mean value over every direction of observation in the Keller cone, as well as in the special direction of backscattering. We employ the incremental length diffraction coefficients for a wedge with finite sized faces based on equivalent edge currents derived recently for truncated wedge strips. The numerical behaviour in the limiting cases of the diffraction coefficients are discussed extensively.
