Modeling of electromagnetic behavior of composite thin layers using genetic algorithm

Abstract In this paper, a new hybrid model is presented using the high frequency electromagnetic simulator for several binary mixtures where the load is in the lossless and thin film form with a permittivity of ( ϵ = 100, 200, 300, and 400) and for various thickness values in a range of 10 μ m to 250 μ m . This model operates in a variety of frequencies from 8.2 GHz to 12.4 GHz. The effective permittivity of composites is evaluated using Nicholson Ross Weir (NRW) algorithm in a rectangular waveguide. The implementation of NRW algorithm is conducted on various samples simulated in order to estimate the dielectric composite behavior. Furthermore, a genetic algorithm methodology (GA) is employed for the optimization of filling factors of the proposed model by Wiener law. The obtained results show a good agreement with Mosallaei model, which ensure the validity of our proposed model based on GA for characterizing the electromagnetic behavior of dielectric thin layers.
