GEMS Software Package
 
GEMS parallel time domain and frequency domain solvers
GEMS is accurate, fast, reliable using the least computer resource
Compatible to other serial or parallel EM simulation software
GEMS allows you to import the 2-D and 3-D models that are generated in other EM software packages or 3-D modeling software packages.
GEMS can export the 2-D and 3-D models into SAT file format and then import the SAT model into other EM simulation software packages.
Using advanced memory allocation, GEMS is fast and requires much less memory than other EM software.
GEMS can be installed on your desktop, laptop, workstation, cluster or supercomputer.
GEMS supports Windows (32/64-bit) and Linux (32/64-bit) operating systems.
 

Product Description
Using GEMS, you can efficiently and accurately simulate antennas, antenna arrays, microwave circuits, packaging, RCS, bio-electromagnetic problems, and other EM problems. The friendly user interface of GEMS allows you to easily create a complex model or import CAD files to GEMS interface. GEMS can use all the resource in your PC to efficiently simulate the EM problems.
