Abstract
- In this paper, an alternative algorithm for simulating metamaterials under a narrow bandpass condition is proposed. To calculate metamaterial regions with unique double negative property, the Drude model is used to solve the constitutive relationship. The effectiveness of the proposed algorithm over existing methods is demonstrated in terms of accuracy, efficiency, and simulation of absorption. For the numerical example, a metamaterial slab with a dipole antenna model is introduced. Compared with previous works, the numerical results indicate that the proposed algorithm is considerably efficient and simulates absorption. Most importantly, the algorithm can maintain stability and reduce simulation duration. [ABSTRACT FROM AUTHOR]
