The modified difference equation near the sharp metal edge in FDTD grid is presented in this paper.In order to test the efficiency of new FDTD equations
we use a stripline and V-shape antenna
which have two sharp edges diagonal to the cell cube in FDTD grid.Compared with staircase approximation
a dramatic improvement in computed accuracy is observed.
