GEMS is a unique EM simulation software that includes many advanced features and techniques in both the graphical interface and EM simulation solver
Waveguide Filter
High-Q microwave component with five cavities. The GEMS can complete the simulation in 2 minutes for an accurate result.
Patch Antenna Array
Optimize the distance between ground and patches to reach a good antenna performance. The simulation includes the feed network.
Confirmal Surface Current
GEMS uses the confirmal technique to calculate the surface current distributon on the curved surfaces of a large PEC body. The confirmal current distribution can be displayed using a regular laptop even for a very large geometry.
Flat FSS Screen
GEMS FSS solver is used to analyze the FSS structure, which can include single layer FSS screen or multiple FSS screens. For the thin slot problem, FSS solver is more efficient than the time domain solver.
Cloak (Metamaterial)
A cloak structure constructed by the PEC open rings. An oblique plane wave incident on it can go through the cloaking structure without reflection at the specified frequencies.
Ground Penetrate Radar (GPR)
A pair of Bow-tie antennas are located above the soil to extract the scattered signal of the buried plastic pipe.
MIMO Antenna
MIMO antenna includes two PIFA structures, and the outputs include, far field patterns, MEG and ECC. The domain dimensions in the horizontal and vertical directions are 110mm and 0.2mm, GEMS can be almost 40 times faster than commercial MoM code.
Extremely Large Problem
GEMS Parallel processing technique allows you to simulate the extremely large problems in the efficient manner. With GEMS hardware acceleration techniques, you can complete a very large problem with a simple workstation.
Radome with FSS Coating
Combining GEMS time domain and frequency domain solvers, we analyze the antenna array with radome coated by the FSS screen. GEMS FSS solver is used to fast analyze the flat FSS problems and the time domain solver is used to simulate the practical problem structures.
Microwave Component
A three-port microwave filter filled with a metamaterial structure. The output parameters include the S-parameters, field propagation animation.
Dual Mode Horn Antenna
A dual mode horn antenna includes three parts. A TE11 mode is used to excite the antenna. The outputs include 2-D and 3-D far field patterns, field distributions, and return loss.
SAM Head Model
The SAM head model with a cell phone antenna. The outputs includes 1-g SAR, 10-g SAR, local SAR, far field patterns, 3-D SAR distributions, and return loss.
GEMS Workstation
GEMS workstation is specially optimized for the EM simulation with the hardware acceleration option, and it can be four times faster than the similar workstation. It can achieve up to 900 Mcells per seconds.
Antenna, Radome and FSS
We are usually interested in the performance of the antenna or antenna array inside the radome with without FSS coating. For the regualr EM solver, the radome or curved FSS structures are big problem, it is impossible to simulate the antenna with radome and FSS screen. However, GEMS allow you to simulate the whole system without using the approximation.
