Abstract: Embodiments herein describe connecting an ASIC to another integrated circuit (or die) using inter-die connections. In one embodiment, an ASIC includes a fabric sliver (e.g., a small region of programmable logic circuitry). Inter-die fabric extension connections are used to connect the fabric sliver in the ASIC to fabric (e.g., programmable logic) in the other integrated circuit. These connections effectively extend the fabric in the ASIC to include the fabric in the other integrated circuit. Hardened IP blocks in the ASIC can then use the fabric sliver and the inter-die extension connections to access computer resources in the other integrated circuit.

Abstract: Various examples are provided for flat lens antennas and their operation. In one example, among others, an antenna includes electrically thin (W<<?high), highly conducting, TEM mode antenna arms fed at a first end by a balun. The TEM mode antenna arms can be embedded in a spatially varied anisotropic dielectric material. A separation between the TEM mode antenna arms can increase from the first end to a second end where the TEM mode antenna arms transition to resistive card (Rcard) terminations when the TEM mode antenna arms are separated by a distance Hr, where a ratio of Hr to a height (H) of the antenna is in a range from about 0.2 to about 0.8.

Abstract: An electromagnetic chamber absorber provided improved absorption across a wideband and both lower diffuse and specular scatter and a method for constructing the same. An exemplary device can compromise a periodic arrangement of disconnected electromagnetically lossy elements where the periodicity of the lattice is adjusted to suppress all or most grating lobe scattering. Because the electromagnetically lossy elements are disconnected, scalable manufacturing approaches are enabled. The lossy elements can be easily fabricated via shaping, which includes rolling, folding and cutting resistive and/or magnetic sheet materials. The lossy elements can be repeatably placed in a periodic lattice using low density scaffolding approaches and/or other alignment mechanisms. The absorption at the lower frequency part of the electromagnetic bands (below 1-2 GHz) can be improved via the addition of parallel lossy sheets into the low-density scaffolding.

Abstract: Various examples of methods and systems are provided for traveling wave spot probes. In one embodiment, among others, a traveling wave spot probe includes one or more antennas positioned proximate to a coated surface. The one or more antennas can be configured to excite a surface traveling wave moving over an area under test by launching radio frequency (RF) energy at approximately a grazing angle to the coated surface under test. The one or more antennas can be positioned on a base placed proximate to the coated surface. The base can define the area of the coated surface under test. In another embodiment, a method for non-destructive testing of a coated surface includes positioning one or more antennas proximate to a coated surface and exciting a surface traveling wave over an area under test by transmitting RF energy via at least a portion of the one or more antennas.

The communications apparatus is configured to generate commands for transmission to the first communication satellite and the second communication satellite to steer respectively first and second spot beams to track and communicate with a user terminal during respective time intervals. The communication interface is also configured to determine a trajectory of the user terminal and a predicted handoff point on the trajectory for handoff between the satellites in which the second spot beam is automatically steered to the handoff point or a point proximate thereto no sooner than the user terminal is within the second spot beam when steered to the predicted handoff point.

Abstract: A method and apparatus for producing ordered parts by from non-ordered liquid crystal monomers. Liquid crystal monomers contain stiff, rod-like mesogenic segments which can be aligned by an external force such as shear, electric field or magnetic field, causing an anisotropy in properties. When cured in the aligned stated by photopolymerizing the aligned monomers the anisotropic structure is “locked in” resulting in materials with anisotropic physical and mechanical properties. The rigid structure of the mesogenic segments can result in cured networks with high glass transition temperatures if the spacer groups which connect the mesogenic core with the reactive end groups are kept short. Glass transition temperatures of postcured parts ranged from 75 to 148° C. depending on resin and processing conditions. A mechanical anisotropy on the order of two was measured for aligned samples.
