Abstract | This paper presents a fast method for electromagnetic scattering and radiation problems pertinent to threedimensional (3-D) buried objects. In this approach a new symmetrical form of the Green's function is derived which can reduce the number of Sommerfeld integrals involved in the buried objects problem. The integration along steepest descent paths and leading-order approximations are introduced to evaluate these Sommerfeld integrals which can greatly accelerate the computation. Based on the fast evaluation of Sommerfeld integrals the radiation of an arbitrarily oriented electric dipole buried in a half space is first analyzed and computed. Then the scattering by buried dielectric objects and conducting objects is considered using the method of moments (MOM). Numerical results show that the fast method can save tremendous CPU time in radiation and scattering problems involving buried objects. © 1999 IEEE. |
