Electromagnetic interference attenuation in a structure with double modal redundancy

This paper examines a method for enhancing the fault tolerance of radio-electronic equipment, termed modal redundancy, which combines the principles of redundancy and modal filtering. The essence of this method lies in utilizing strong electromagnetic coupling between two or more redundant conductors to mitigate electromagnetic interference. This approach offers several advantages, as the system can continue to operate even in the event of failure of one or more conductors, which is crucial for ensuring uninterrupted device operation. The modal redundancy method is effective in situations where it is necessary to minimize the risks of signal loss and reduce the impact of interference, making it valuable in various fields where high operational stability of equipment is required. Research Objective: To investigate the characteristics of asymmetric structures implemented using double modal redundancy and to evaluate their effectiveness under various operating conditions.
