Application of stable FEM-FDTD hybrid to scattering problems.

Application of stable FEM-FDTD hybrid to scattering problems.

A recently developed, stable, finite-element method (FEM), finite-difference time-domain (FDTD) hybrid that eliminates the staircase approximation of complex geometries is tested by convergence studies for radar cross-sections. For a conducting sphere, 1 dB accuracy in all directions is obtained wit...
