Abstract
A finite-volume (FV) method is introduced to solve the time-domain (TD) Maxwell equations with applications to handle scattering problems of several classic perfect electrical conductors including cylinder, airfoil in 2D cases and sphere, cube and dual spheres in 3D cases. Spatial discretization and time integration involved are implemented by adopting approximate Riemann solution and two step Runge-Kutta method respectively. Reconstruction schemes for structured grids in 2D case and adaptive Cartesian grids in 3D case are presented successively. The computational results agree quite well with the theory values, measurement data as well as results from references.
