Rotman Lens |
|
The Rotman lens has the dimensions, 580 mm x 500 mm x 4.56mm, which is discretized into 1744 x 1795 x 10 non-uniform cells. The memory requirement is only 3.4GB and it took 119 minutes for GEMS to simulate it on a PC cluster. The input port is excited using TE10 mode and the transmitted power at output ports is measured. |
