===Planewave Source===
Since we're computing a Radar Cross Section, we also need to add a planewave source. For this example, we will specify a TMz planewave with k = sqrt(2)/2 x - sqrt(2)/2 z, or theta = 135 degrees, phi = 0 degrees.

===Mesh Settings===
At 850 MHz, the resulting FDTD mesh is about 270 million cells. With mesh-mode on in [[EM.Cube]], we can visually inspect the mesh.
