Paper Abstract
Previous efforts to create a metamaterial lens in the microwave X band frequency range focused on the development of a
device with biaxial symmetry. This allows for focusing solely along the central axis of propagation. For applications
involving wave direction or energy diversion, focusing may be required off the central axis. This work explores a
metamaterial device with uniaxial symmetry, namely in the direction of propagation. Ray-trace optimization and full-wave
finite element simulations contribute to the design of the lens. By changing the placement of the focus, we achieve
further control of the focus parameters. While the present work uses coils, the unit cell can consist of any structure or
material.
