Abstract
In this paper, for the design and processing of electromagnetic wave absorbing Nano coatings, we have studied various factors in creating the property of absorbing waves in polymer paints and identified the materials that are commonly used in this field. In this research, the imitation-based optimization algorithm has been used. To conduct this research, first, the types of absorption methods and radar frequencies used were extracted and it was determined that by using external electromagnetic field radiation on composite materials and considering the boundary conditions of radiation waves, a different structure of materials can be observed. In this study, samples of epoxy paint and lanthanum aluminate (LaAlO3) Nano powder were applied and the absorption percentage of this sample was measured using a network analysis device. For lanthanum aluminate sample, the reflectance loss was -13.8 dB, equivalent to the absorption coefficient of 83%.
