Analysis of Angular Stability of Fractal Artificial Magnetic Conductor Metasurface Using Generalized Boundary Conditions

Résumé

In this work, an Artificial Magnetic Conductor (AMC) metasurface composed by a Sierpinski Carpet fractal unit cell is analyzed using the Generalized Boundary Conditions (GBCs). Since the fractal structure cannot be represented using analytical expressions, the detailed GBCs model is presented to analyze angular and polarization stabilities of the obtained metasurface. The angular stability of the fractal geometry is compared with the square loop and Jerusalem Cross geometries, from the stable bandwidth and frequency deviation. Finally, the computational effort and the accuracy of the proposed method is compared to conventional methods through performance parameters, thus validating GBCs as an alternative method to characterize AMCs.
