摘要： A single or multilayer optical interference filter and method of forming filter by ion implantation. One or more layers of nitrogen ions are implanted into a single crystal silicon with the crystal at a temperature of from about 600.degree. C. to about 1000.degree. C. The implanted ions create a buried layer(s) of silicon nitride (Si.sub.3 N.sub.4) whose refractive index is substantially different from that of silicon (Si) such that appreciable multiple reflection of incident light occurs between the buried layer(s) and the front surface. The resulting interference maxima and minima in transmitted or reflected light which occur at well-defined positions in wavelength may be controlled both in amplitude and wavelength position. The ions may be implanted in layers at different depths to produce a "thin film" interference filter.

摘要： A composite armor plate includes a fracture layer placed adjacent to a ceramic layer. The ceramic layer provides a ballistic resistant layer that receives a ballistic impact and propagates a compression wave. The fracture layer is placed behind the ceramic layer and absorbs a portion of the compression wave propagating out in front of the ballistic impact. The absorbed compression wave causes the fracture layer to at least partially disintegrate into fine particles, which dissipates energy in the process. To cause a higher degree of fracturing (and thus larger dissipation of compression wave energy) the fracture layer includes a plurality of resonators embedded in a fracture material.

摘要： An apparatus and method for producing films of silicon nitride whose index of refraction varies continuously with film depth by preselected amounts between n=3.9 and n=1.99. This is done by producing an amorphous film of silicon nitride, Si.sub.1-x N.sub.x, of pre-selected stoichiometry between x=0 and x=0.57. In a vacuum-chamber, a target substrate is exposed to vaporized silicon while being simultaneously bombarded with an ion beam of relatively high kinetic energy, ionized, nitrogen particles. The nitrogen embeds in the silicon film deposited on the substrate to form amorphous silicon nitride, the stoichiometry of which depends on the intensity of the ion beam. Instruments measure during the deposition the relative rate of arrival at the target for silicon and nitrogen, and, with pre-generated calibration data for the apparatus, enable an operator to selectively control the film's stoichiometry by controlling the ion beam's intensity response to the measured rate of silicon deposition.

摘要： A system for reducing the effects of a blast wave includes armor plating configured to face a supersonic blast wave. The armor plating has a surface consisting of alternating tall and short peaks with valleys between the peaks. The peaks and valleys are positioned such that the supersonic blast wave reflects from the side surfaces of the tall peaks as a regular reflection that at least partially suppresses Mach reflection of the supersonic wave caused by the short peaks and the valleys. The surface may also be designed to not trap reflected waves. The valleys can be parabolic shaped to deflect and/or dissipate transonic flow that follows the blast wave front.
