Abstract: An antenna includes a metal 3D printed array of radiating elements configured as a unitary arrangement of a metal reflector, a plurality of metal support stalks extending forwardly of the metal reflector, and a plurality metal radiating arms attached to distal ends of corresponding ones of the plurality of metal support stalks. The unitary arrangement also includes a plurality of 3D printed metal feed stalks, which extend forwardly of the metal reflector and contact corresponding ones of the plurality of metal radiating arms, a 3D printed metal filter chassis on a rear-facing surface of the metal reflector, and 3D printed array of cavity filters with resonators within the metal filter chassis.

Abstract: Indium-based interface systems, structures, and methods for forming the same are provided. The disclosed indium-based interfaces may be formed as solid structures between two solid surfaces by providing a solid indium-based material between the two surfaces, and heating the indium-based material above its melting point while in contact with each of the two surfaces to cause the indium-based material to reflow or otherwise liquefy between the two surfaces. The indium-based material may then be cooled below its melting point to form a solid interface material structure that is positioned between and in contact with each of the surfaces.

Abstract: An intraocular lens (IOL) device includes a lens configured to be positioned along the optical axis of a patient's eye and at least one haptic configured to engage an area within the patient's eye in order to position the lens along the optical axis. The IOL device further includes an expandable haptic-lens junction coupling the at least one haptic to the lens, the expandable haptic-lens junction configured to displace the lens relative to the haptic in response to an applied energy.

Abstract: A hardware-based acceleration platform for computational electromagnetic algorithms, specifically the finite-difference time-domain (“FDTD”) method, comprises reformulating the FDTD algorithm in order to make it more hardware friendly. This reformulation makes use of split fields at every node in the mesh, and combines total- and scattered-field formulations into a single, hybrid formulation. By precomputing coefficients for the nodes in the mesh, it is possible for a single set of equations to support plane waves, point sources, PML ABCs, and PEC walls. In the method sources are determined by means of a lookup table, rather than through direct hardware computations. All of these modifications enable the hardware designer to much more easily develop an FDTD accelerator.

Abstract: Disclosed herein is an organization of cache memory for hardware acceleration of the FDTD method. The organization of cache memory for hardware acceleration of the FDTD method provides a substantial speedup to the finite-difference time-domain (FDTD) algorithm when implemented in a piece of digital hardware. The organization of cache memory for hardware acceleration of the FDTD method utilizes a very high bandwidth dual-port on-chip memory in a particular way. By creating many small banks of internal memory and arranging them carefully, all data dependencies can be statically wired. This allows for a many-fold speedup over SRAM-based solutions and removes the burden of data dependence calculation that streaming SDRAM-based solutions must perform.
