Feko

High-Frequency Electromagnetic Field and Antenna Design

       Feko is a world-leading electromagnetic field simulation tool that employs multiple frequency-domain and time-domain techniques. These truly hybrid solver technologies can efficiently analyze a wide range of broadband electromagnetic problems related to antenna design, antenna placement, electromagnetic scattering, radar cross section (RCS), and electromagnetic compatibility (EMC), including electromagnetic pulse (EMP), lightning effects, high-intensity radiated fields (HIRF), and radiation hazards.

 

【 Product Highlights 】

• A general-purpose electromagnetic simulation tool covering antenna design, antenna placement, and radar cross section (RCS)

• EMC (electromagnetic compatibility) analysis capabilities, including radiation, susceptibility, and shielding effectiveness

• Rich hybrid solution methods for electrically large structures and complex problems

• Dedicated tools for windscreen antennas, arrays, cable harnesses, and characteristic mode analysis

• Efficient, reliable, and accurate parallel solvers

【 Advantages 】

One Product, Multiple Solvers
       Feko supports flexible selection among multiple solvers. Users can choose the most appropriate method for each problem and can also cross-verify results with different methods. Feko solvers can be purchased individually or via the HyperWorks licensing system.

True Hybrid Solvers
       Feko provides industry-leading hybrid solvers. These hybrid technologies are more efficient and accurate for analyzing multi-scale problems involving complex media andelectrically large structures.

Solver Accuracy and Performance
       Extensive validation and enhancement of the numerical methods in Feko ensure the correctness of the approaches used. Continuous optimization of solver performance and parallel acceleration delivers industry-leading computational efficiency.

Specialized Solutions
       Feko was the first commercial software to provide a characteristic mode analysis (CMA) solver and remains the most mature and reliable solution in this area. Feko includes dedicated solvers for bidirectional coupling with cable harnesses, windscreen antennas, and finite arrays. Workflow based on modal decomposition helps address antenna placement and EMC problems by using equivalent sources to represent transmitting/receiving antennas and other devices.
