  • Patent number: 8902115
    Abstract: A resonant dielectric metamaterial comprises a first and a second set of dielectric scattering particles (e.g., spheres) having different permittivities arranged in a cubic array. The array can be an ordered or randomized array of particles. The resonant dielectric metamaterials are low-loss 3D isotropic materials with negative permittivity and permeability. Such isotropic double negative materials offer polarization and direction independent electromagnetic wave propagation.

  • Patent number: 8547287
    Abstract: Provided is a circuit for an electronic device having a non-planar transparent resonator. The transparent resonator is mounted on said circuit so as to at least partially occupy a footprint of another component of the circuit. The transparent resonator forms part of a light pathway on said circuit for transmitting light to or from said another component. Also provided is a transparent dielectric resonator antenna (DRA) for optical applications. Since the DRA is transparent, it can let light pass through itself and, thus, the light can be utilized by an optical part of a system or device. The transparent DRA can be placed on top of a solar cell. Since the DRA does not block the light, the light can reach the solar cell panel and power can be generated for the system or device. The system or device so obtained is very compact because no extra footprint is needed within the system or device for the DRA. It finds application in compact wireless applications that need a self-sustaining power device.

  • Patent number: 8504135
    Abstract: Embodiments of endfire aperture-based traveling-wave antennas are described. For example, an embodiment, including a Vivaldi antenna, may have a director incorporated into the aperture region of the antenna to provide enhanced radiation directivity. The director may be a shaped dielectric that interacts with an electromagnetic field to reduce the divergence of the resultant beam as it exits the antenna. Additional dielectric substrate layers may be stacked on both sides of the antenna in order to balance the dielectric loading between the different conductors. The dielectric substrates may also eliminate contact between the antenna metallization and the lossy environment. Certain disclosed Vivaldi antennas may be used in tissue screening applications.
