Static RCS of a PEC cylinder can be computed through Mie series. Here, we use GEMS to predict both the monostatic and bistatic RCS of 2-D PEC cylinder. The radius of cylinder is 25 mm and illumined by a plane wave from the X-direction. The outputs from GEMS package is 2-D RCS distribution and time signature of far field and the incident field of the plane wave is listed in the excitation entrance in the display module. You can directly plot the bistatic RCS and colculate the monostatic RCS through GEMS data processing center.
Since the cylinder is infinitely long inone direction, therefore, GEMS can only need to simulate a cross section of cylinder and the result will be for the infinitely long cylinder.
The hardware paltform for this simulation is two dual core 2.33GHz computers and it toke 15 seconds to simulation this problem. The problem size is 74x74x1and memory requirement is 10 MB.
