This antenna array is not a small problem for other EM simulation software. However, GEMS requires less than 10GB memory and can complete the simulation in approximately 2 hours.
High Speed Chip
GEMS simulates an eight-layer chip using less than 5 hours and 10 GB memory. The high performance CPML only requires 2 cells of white space for the accurate and stable results.
Microwave Filter
A power divider includes one excitation port and 18 output ports. The simulation requires less than 1GB memory and is completed in 3 hour and 56 min.
Bio-Human Head Model
The bio-human head model, part of Brooks segmented visible human model, is simulated with a nearby dipole antenna. 3-D SAR allows you to view the SAR in any region inside the human head.
Rotman Lens
A Rotman lens includes 17 excitation and 39 output ports. GEMS simulates it in 1 hour and 59 minutes using 3.4GB memory.
64-Element Helix Antenna Array
GEMS simulates 64 element helix antenna array with dielectric supports, PEC isolation skirt and a feed network. The simulation can be completed in about 3 hours using only 4 GB memory.
