DESCRIPTION:EM diffraction is critical in many applications including anten
 nas and propagation. Understanding and visualizing EM wave – object inte
 raction is crucial in designing new antenna systems\, in predicting path l
 osses through complex propagation paths\, etc. In order to do that wave pi
 eces such as diffracted waves\, Fringe waves\, etc.\, should first be stud
 ied on canonical structures. Then\, complex objects can be investigated by
  using HFA as well as numerical methods in hybrid form intelligently.\n\nE
 M wave scattering from waves – objects interaction has long been investi
 gated. Interesting wave phenomena\, diffraction\, occur when objects have 
 sharp edges and tips. Methods known as High Frequency Asymptotics\, such a
 s Geometric optics (GO)\, Physical Optics\, (PO)\, Geometrical Theory of D
 iffraction\, (GTD)\, Uniform Theory of Diffraction (UTD)\, Physical Theory
  of Diffraction (PTD) and Theory of Edge Diffraction (TED) have been succe
 ssfully applied to variety of EM problems. Recently\, numerical methods\, 
 such as Finite Difference time Domain (FDTD)\, Method of Moments (MoM) and
  Finite Element Method (FEM) have also been used in modeling EM diffractio
 n. These powerful methods\, together with novel approaches\, have shown to
  be successful not only in modeling EM diffraction but also in distinguish
