Optically transparent ground planes with high order response using miniaturized element frequency selective surfaces

In this paper design of a multi-pole wide band optically transparent ground plane is considered. Challenges of the design by stacking multiple layers of single pole miniaturized element frequency selective surfaces are explained. An alternate arrangement of the layers and spacing between the layers is proposed. A three-pole transparent ground plane is designed band fabricated based on the proposed technique. The performance of the designed ground plane using analytical and computational methods is evaluated experimentally and excellent agreement is demonstrated.
