RADAR absorption materials (RAMs) and coatings have been widely used in stealth technology since World War\nII. Stealth refers to the ability to evade from the detection from any kind of radar detection. Radar absorbing materials have\nfound a significant importance in today’s stealthy Therefore, numerous research works have been done to pursue a highperformance\nabsorber to solve the electromagnetic pollution problem. Thus with advancement it has been invented that the\nfrequency selective surface embedded in the layers of radar absorbing material has better absorption than the normal ones.\nBut till now the proposed different geometric structures or the use of lumped elements in the material so far has one or the\nother limitation. So this work has been proposed to find the best trade off between the maximum absorption bandwidth and\nminimum material thickness with the use of particle swarm optimization and also compares the results of with and without\nlumped elements. The proposed comparison and results of optimization are in good agreement.
