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)
