![]() ![]() For example, to add a perfectly conducting wire segment to a cell edge, the equation for computing the electric field can be replaced by simply setting the field to zero since the electric field in a perfect conductor is identically zero. Within the mesh, materials such as conductors or dielectrics can be added by changing the equations for computing the fields at given locations. Each cell will also have three magnetic fields originating on the faces of the cell adjacent to the common node of the electric fields as shown in Figure 1. The electric fields at the other nine edges of the FDTD cell will belong to other, adjacent cells. Each FDTD cell will overlap edges and faces with its neighbors, so by convention each cell will have three electric fields that begin at a common node associated with it. When many FDTD cells are combined together to form a three-dimensional volume, the result is an FDTD grid or mesh. ![]()
