E-MIND: Electromagnetic Multicode Integrated Design Framework for EMI/EMC risk analysis and mitigation

E-MIND provides an integrated environment for aeronautical EMC/EMI risk assessment and mitigation. It allows aircraft manufacturers to create electromagnetic (EM) models of aircraft designs, to assess the performance of different antennas and arrays, and to optimize the design of an aircraft through testing alternative antenna locations.

E-MIND includes a range of prediction tools covering the full operational spectrum of modern aircraft. These tools can be used to perform system level antenna performance evaluations, EMI assessment and reduction, and communication link quality verification. They have been extensively validated through IDS’s experience providing aeronautical measurement and consultancy services over the last 25 years. Feedback from IDS’s engineers is also used to continuously update and improve E-MIND’s tools and working procedures with the aim of reducing the time and cost of an optimized avionic design solution.

E-MIND provides a full framework for project workflow and management, and provides design history and modification tracking as well as version control, allowing multiple users to work on the same project. It includes tools to interface with most common commercial CAD software as well as an advanced meshing tool to generate numerical models to be used by the EM solvers.

The E-MIND framework is based on a client-server software architecture: the client side where pre- and post-processing functions are performed, and the server side where electromagnetic analyses are run. This architecture allows several configurations to meet the user's needs:

  • Single Client / Single Server (the simplest E-MIND installation, to manage small/medium size targets)
  • Single Client / Multiple Servers (single user and large computational resources, to manage large size targets)
  • Multiple Clients / Single Server (multiple users, to manage small/medium size targets)
  • Multiple Clients / Multiple Servers (multiple users and large computational resources, to manage large size targets)


  • Pattern distortion analysis; assessing the effects of an aircraft’s body and attachments on an antenna’s free space pattern;
  • Full system EMC/EMI risk assessment and mitigation;
  • Antenna and array modeling and siting optimization;
  • Self-coupling, in-band and out of band inter antenna coupling;
  • Link budget evaluation; assessing the effective performance of telecommunication transmitters and receivers including environment modeling (atmosphere attenuation, reflection from earth surface);
  • Performance evaluations compliant with civil aviation authority and international standards e.g. ICAO, FAA, EUROCAE, RTCA;
  • Airborne radome performance assessment (RTCA DO-213);
  • High Intensity Radiated Fields (HIRF) analysis; ensuring that electronic systems are protected against the threat of malfunction or failure caused by HIRF environments;
  • Indirect effects of lightning on aircraft electronic systems prediction;
  • Harness modeling (3D arbitrary path), disturbance propagation and transient analysis on cables.


  • Specific features for aeronautical applications;
  • Multiple prediction tools including Method of Moments (MoM), Multi Level Fast Multipole Method (MLFMM), Uniform Theory of Diffraction (UTD), Physical Optics (PO) and Incremental Theory of Diffraction (ITD);
  • A comprehensive meshing tool with user friendly healing and cleaning capabilities and advanced meshing functions;
  • A dedicated CAD environment for array layout definition and excitation specification;
  • Fast and detailed design modeling procedures for avionic antennas and arrays: Method of Moments for arbitrary shaped dieletrics, acceleration methods for full-wave analysis of large array (SIM, SFX, SM-AIM, SIM/SFX, SFX/SM-AIM), equivalent models (Huygens sources, spherical wave expansions) etc;
  • Multi transmission line method for harness analysis;
  • Power balance based procedure for statistical evaluation of field distribution in overmoded cavities such as avionic bays (radiated emission / radiated susceptibility analysis);
  • Database of validated avionic antennas with the ability to import user defined antennas;
  • Automatic computational management and workload balancing to optimize resource usage and to reduce computational time;
  • Intuitive workflow.
