Boost your vision with • D equivalent electric and magnetic current 3 distribution reconstruction • nnovative algorithm approach I • utting-edge 3D viewer C Thanks to an innovative formulation of the inverse electromagnetic problem, INSIGHT is the first software able to compute authentic electromagnetic current distributions and extreme near fields on your antenna under test from measured near-field or far-field da

Key Features INSIGHT owns a set of unique features opening the way to numerous capabilities of analysis and diagnosis. General • Native Graphical User Interface based on Windows XP, Windows Vista, Windows 7 • High accuracy results proven by extensive validation campaigns • Fast Multipole Method (FMM) for investigating even large antennas • Applicability to any antenna measured data, such as Near Field (NF) data (Spherical, Planar, Cylindrical) and Far Field (FF) data • Link for importing the computed EM antenna models to the CEM software CST, Savant, Ansys HFSS, FEKO and ADF Measurement...

In the antenna design or EMC testing process, the measured radiation pattern or shielding performance does not always correspond to what is expected. Identifying the source of the discrepancies can be a time-consuming process. With INSIGHT, you can reconstruct the equivalent currents and extreme near-field on the antenna: it allows for quick and clear identification of the cause of problems observed during measurement. Further post-processing tools are available for in-depth investigation. Clearly understanding radiation characteristics eases development and shortens time to market. Key...

LINK BETWEEN INSIGHT AND NUMERICAL CEM TOOLS

INSIGHT step by step ➊ OMPUTATION OF THE EQUIVALENT CURRENTS, FILTERING AND NEAR-FIELD C COMPUTATION. Step 1: Load measurement data and import/create the geometry: Step 2: Perform the measurement post-processing and visualize the results: • oad the measurement data: near-field (NF), L far-field (FF) or both • onfigure the measurement data C nd the geometry a • Manage the geometry for the current/field reconstruction: - Import CAD or mesh files - raw a generic geometry using the CAD D functionalities • erform the INSIGHT measurement P post-processing With the visualization functionalities,...

Step 3: Investigate the problem in-depth by post-processing the INSIGHT results: ➋ REPARATION OF A NF SOURCE P FOR CEM TOOLS • ilter unwanted currents after the diagnostics F - Switch off” the electrical and magnetic “ reconstructed currents on a selected area of the reconstruction geometry. Example: Dual Ridge Horn SH4000 feeding a reflector antenna. • fter measurement of the source antenna (SH4000), A - load the measurement data: near-field (NF) far-field (FF) or both; - create a geometrical surface as a box; Ò - Compute the radiated field from the filtered current - Compare the...
