Electromagnetic interference shielding design using real-coded genetic algorithm and reliability evaluation in X-band

Abstract

The increased deployment of various electrical and electronic equipments/devices for the commercial, industrial, and military systems has created a number of sources and receptors of electromagnetic interference that can degrade the system performance or affect safety operation of intelligence/secrecy between the various services. To avoid the interference problems from the adverse effects of electromagnetic waves, there is a greater need for shielding of these equipments/devices. In this paper, a design approach to meet the military requirement shielding for multi-layer electromagnetic shield is described. This design problem is solved by using shielding effectiveness theory based on transmission line modeling and real-coded genetic algorithm with simulated binary crossover and parameter-based mutation. Further, it is shown that by using Monte Carlo simulation, the performance of electromagnetic shielding under the uncertain operating conditions can be evaluated in terms of reliability. © 2012 Springer India Pvt.
