Bianisotropic metamaterial

DWPI Title: Bianisotropic metamaterial comprises upper and lower rings that are concentric and spaced apart from each other perpendicular to planar direction and rotated by specific angle with respect to each other
Abstract: The topology of the elements of a metamaterial can be engineered from its desired electromagnetic constitutive tensor using an inverse group theory method. Therefore, given a desired electromagnetic response and a generic metamaterial elemental design, group theory is applied to predict the various ways that the element can be arranged in three dimensions to produce the desired functionality. An optimizer can then be applied to an electromagnetic modeling tool to fine tune the values of the electromagnetic properties of the resulting metamaterial topology.
Use: Bianisotropic metamaterial.
Advantage: The ease of fabrication is ensured and the ability to independently modify the electric and magnetic response is facilitated. Since the resonant frequency is shifted over a relatively large range without having to change the period of the metamaterial, the additional degree of freedom in tuning the behavior of the metamaterial is provided and effectively relaxation of the constraints for fabrication is ensured.
Novelty: The metamaterial comprises an upper planar electrically conducting ring with two opposing capacitive arms. The opposing fingers are intersected and oriented perpendicular to upper ring with specific symmetry. A lower planar electrically conducting ring is provided with two opposing capacitive arms. A conducting rod is passed through center of the lower ring. The upper and lower rings are concentric and spaced apart from each other perpendicular t planar direction and rotated by specific angle with respect to each other to provide a metamaterial element with the specific symmetry.
