With the  relentless circuit speed increasing and  wide applications of microelectronics in telecommunication, automotive and aerospace industry, electromagnetic environment within these systems is  increasingly becoming more and more complex,   satisfaction with the electrical performance as well as the  stringent standardized requirements on system emission and susceptibility, electromagnetic simulation and analysis  prior and after the system design and fabrications becomes an indispensable step.  However, the present single simulation  tools are inefficient to solve large electromagnetic problems when the object has a complex and large structure with respect to the wavelength of the frequency of interest.  COMEM SOLVER is an effective simulator  for electromagnetic problems with large and complex structure.  EMC SOLVER has implemented the domain-decomposition technique with   integrated the full-wave numerical methods and the asymptotic methods such as PO and UTD to address the complex and large EM problems.

Features 

·          For objects with a large electrical capacity, asymptotic methods such as PO and UTD are applied together with full-wave methods to extend the electrical size of the object.

·          For objects with complex structure, full-wave methods are applied together with the asymptotic methods to address the EM field distributions for critical and important regions to give accurate results. 

·          Provides fast and efficient solutions for Electromagnetic Compatibility (EMC) problems

·          Reduces the requirements on computer memory through different hybridized methods, which make the simulation of large scale EM problems (on a scale of thousands of wavelengths) possible

·          Reduce simulation time and engineering analysis cost through high-performance EMC modelling and post-processing

·          Results from the simulation rendered, EM fields, radiation pattern, coupling, S-parameters, etc.

Applications

COMEM Solver is applicable to various electromagnetic problems such as automotive, aircraft and  communication system.
