Abstract
This paper describes the method of optimum design of multilayer perforated electromagnetic shield using Evolutionary algorithms, namely Particle Swarm Optimization Algorithm (PSO) and Genetic Algorithm (GA). Different parameters which are inherently conflicting in nature corresponds to the multilayer structure of the electromagnetic shields have been considered. The goal is to minimize the overall mass of the shield with respect to its shielding effectiveness and cost. Three different models are considered and synthesized using evolutionary algorithms. Numerical optimal results for each model using different algorithms are presented and compared with each other to establish the effectiveness of the proposed method of designing.

In this modern age of electronics Todays world, mostly depends and relies on the technology, which is based on electromagnetic waves and its radiations
This paper mainly focused on the optimum designing of thin wideband (900-1800MHz) perforated multilayer electromagnetic shield using Particle Swarm Optimization algorithm (PSO) [12, 13, 18] and Genetic Algorithm (GA) [11, 13,14,15,16,17]
The shield should capable to minimize the effects of electromagnetic radiation by providing significant shielding effectiveness (SE) having practically possible least effective mass and thickness with low cost is the primary objective of our design, all these design considerations are incorporated in the form of the following objective function for the purpose of optimization
Summary
In this modern age of electronics Todays world, mostly depends and relies on the technology, which is based on electromagnetic waves and its radiations This electromagnetic radiations have very adverse effects related to the human health issues causing various diseases, but it may affect the performance of a device and degrades its efficiency. The electromagnetic shields finds its wide range of applications in various electronic systems such as radar engineering, wireless communication, electromagnetic compatibility and much more These are made engineers and researchers to concentrate more on the optimum design of electromagnetic shield considering various parameters which are inherently conflicting in nature [1,2,3,4,5,6,7,8,9]. Three different models are considered and compared to verify the effectiveness of the proposed design methods
