Abstract :
In this paper, an asymptotic diffraction model for rounded wedges is presented that includes the effect of creeping waves that are launched by a discontinuity in curvature and is valid for uniform field prediction behind the obstruction. A scattering model for a semi-infinite perfectly conducting wedge with rounded edge is presented in R. A. Ross and M. A. K. Hamid (1971) and is applied for lit zone field computation.
