Title: Luneburg Lens Using Metalized Thin Film Dielectrics
Invention: The invention is an improved design of the Luneburg lens structure by changing the metalized pattern on the surface of thin film/wire based dielectrics. Full-wave finite-element stimulations evaluate the effective permittivity of each unit cell. Conductive ink printing or electrical platting fabricated the lens.
Background: A Luneburg lens retains gradient index lines and forms perfect geometrical images of two concentric spheres onto each other. This produces an infinite number of refractive-index profiles. While this allows for use with electromagnetic radiation from visible light to radio waves, current Luneburg lenses are made from different materials, which results in a higher cost and heavier weight.
- Wireless communication
- Remote sensing
- Microwave antennas
- Military defense
- Reduced weight due to the majority of the lens volume being free space
- High performance
