EMPIRE™ is one of the leading 3D electromagnetic field simulators based on the powerful Finite Difference Time Domain Method. Its applicability covers the 3D-EM design and modelling of nearly all passive devices. Especially for multi-layered RF components and for antennas on LTCC. EMPIRE™ has been proven in practice in a huge number of applications. This experience is offered to design RF modules for customers applications.

Highlights are
  • Accurate 3D modeling, utilizing a speed optimized FDTD kernel
  • (Finite Difference Time Domain Algorithm) Easy-to-use interface
  • Import/export of layout data supporting common standards
  • Developed and supported by experienced RF design engineers
  • Proven in practice within industrial and public projects
  • Software and application support available
  • Updated frequently with latest developments in research and new features.
