This article explores efficient electromagnetic (EM) parameters for metamaterials modeled using the Drude theory. Metamaterials are artificially engineered materials possessing extraordinary properties determined by their microstructural configurations. The Drude model incorporates electron-nucleus interactions within materials, enabling more accurate simulations of metamaterials' electromagnetic characteristics. This work discusses methods to optimize metamaterial performance through parameter tuning and analyzes the advantages and limitations of Drude model implementations. Key implementation aspects include computational approaches for solving dispersion relations, algorithms for permittivity/permeability calculations using ω_p (plasma frequency) and γ (collision frequency) parameters, and numerical techniques for optimizing frequency-dependent responses through gradient-based methods or genetic algorithms.
