    Abstract: A communication system that reduces the mutual influence of antennas operating in similar or different frequency bands. The communication system includes a first and a second antenna operating in a first and a second frequency band, respectively, and placed in close proximity to each other. The first antenna is covered by a conformal mantle metasurface with anti-phase scattering properties thereby cancelling the scattering in the second frequency band.

When the first antenna is a low-band dipole antenna and when the second antenna is a high-band dipole antenna, the conformal mantle metasurface reduces the low-band blockage without disrupting the performance of both antennas in terms of radiation pattern and impedance matching.

  • Patent number: 9851477
    Abstract: A non-round fluid lens assembly includes a non-round rigid lens and a flexible membrane attached to the non-round rigid lens, such that a cavity is formed between the non-round rigid lens and the flexible membrane. A reservoir in fluid communication with the cavity allows a fluid to be transferred into and out of the cavity so as to change the optical power of the fluid lens assembly. In an embodiment, a front surface of the non-round rigid lens is aspheric. Additionally or alternatively, a thickness of the flexible membrane may be contoured so that it changes shape in a spheric manner when fluid is transferred between the cavity and the reservoir.

  • Patent number: 9851529
    Abstract: Disclosed is an imaging lens substantially consisting of a first lens group having a positive refractive power and a second lens group having a positive refractive power, arranged in this order from the object side. Focusing is performed by moving the entire second lens group along the optical axis. The most-image-side lens of the first lens group, a lens which is second from a most-image side in the first lens group, and a lens which is third from the most-image side in the first lens group are all meniscus lenses with convex surfaces toward the image side. The imaging lens satisfies the formula: 1.0<FA/FB<8.0, where FA is the focal length of the first lens group, and FB is the focal length of the second lens group.

  • Patent number: 9726979
    Abstract: A catadioptric projection objective has a first objective part, defining a first part of the optical axis and imaging an object field to form a first real intermediate image. It also has a second, catadioptric objective part forming a second real intermediate image using the radiation from the first objective part. The second objective part has a concave mirror and defines a second part of the optical axis. A third objective part images the second real intermediate image into the image plane and defines a third part of the optical axis. Folding mirrors deflect the radiation from the object plane towards the concave mirror; and deflect the radiation from the concave mirror towards the image plane. The first part of the optical axis defined by the first objective part is laterally offset from and aligned parallel with the third part of the optical axis.
