Abstract: Circularly polarized radiation is tapped off from an input waveguide (IWG) through an input iris (a) into an entry cavity (A), where it is resolved into two orthogonal linearly polarized components (H, V). These respectively proceed along two discrete paths to an exit cavity (D). In each path six independently tunable resonances - traversed by both direct and bridge couplings - provide enough degrees of freedom for quasi-elliptic filter functions. In the exit cavity the resultants from the two paths are combined to resynthesize circularly-polarized radiation, which traverses another iris (g) to the output waveguide (OWG). In one layout, four resonant tri-mode cavities form a rectangular array with entry and exit cavities at diagonally opposite corners - and intermediate cavities for the two discrete paths in the two remaining corners. In another layout, six dual-mode cavities form a three-dimensional array: entry and exit cavities stacked one above the other, and two intermediate two-cavity stacks for the two discrete paths adjacent the entry/exit stack.

Abstract: Apparatus for providing microelectronic, intra-chip and chip-to-chip interconnections in an ultra-dense integrated circuit configuration. A chip interface mesa and chip assembly (10) includes a mesa member (12) which has a top planar mesa surface (14) and side walls (16). The perimeter of mesa (12) has a plurality of notches (18) which are each coated with a conductive layer. The notches (18) are electrically coupled to a mesa interface conductive terminals (22) via conductive pathways (20). A semiconductor chip (24) having a top surface (25) bearing active circuitry may be bonded to the bottom of mesa member (12) with an epoxy adhesive. Each notch (18) is aligned with a corresponding conductive interface pad (28) on the top surface (25) of the chip (24). Droplets of solder (26) are placed upon the chip interface pads (28) and are mechanically and electrically coupled to mesa (12) through a conductive layer on each notch (18). The present invention totally eliminates undesirable and wasteful looped wirebonds and provides substantial increases in volume available for active circuitry per planar die area.

Abstract: Methods for forming holes of predetermined size in polyimide substrates having metallic layers adhesively attached thereto include selectively removing areas of desired size and shape from the metallic layer; contacting the exposed adhesive layer with a selective etchant therefor that does not affect the polyimide substrate or undercut the adhesive near the opening formed; and selectively etching the polyimide substrate exposed in the openings by removal of the adhesive layer overlying the polyimides. These methods permit rapid, efficient formation of holes having a diameter as small as one mil (0.00254 cm).

Abstract: An enhanced quadrature notch filter which is capable of rejecting an undesired signal component of an input signal, generally comprising a quadrature phase splitter (16') for producing first and second reference signals which have substantially the same frequency as the undesired signal component but which are 90o out of phase with each other, a pair of amplitude control loops (18', 20') for adding the first and second reference signals to the input signal in amplitudes which will cancel the undesired signal component, and a phase locked loop (36) circuit for maintaining a predetermined phase relationship between the undesired signal component and and one of the first and second reference signals.

Abstract: An internal impedance dependent amplifier has a gain as determined by the impedance at a predetermined node within the amplifier. A PIN diode (42) is coupled to the predetermined node (26). The PIN diode (21) is driven with a forward biased current (Ip) which serves as the accurate gain control signal for the amplifier. In the preferred embodiment, the PIN diode (42) is driven by an operational amplifier (56) in such a manner that the impedance thus coupled to the predetermined node in the amplifier is temperature independent. Because the PIN diode has an impedance given by: log R = A + B log Ip, where R is the impedance of the PIN diode; Ip is the forward biasing current; and A and B constants which are different for each PIN diode, the voltage (Vc) applied to the operational amplifier (56) driving the PIN diode (42) is linear with respect to the impedance of the PIN diode (42) and hence the voltage gain of the impedance controlled amplifier to which the PIN diode is coupled. This characteristic of the gain of the amplifier allows the amplifier to be cascaded in series (A1 ... A11) and to preserve the same impedance relation as expressed above for the cascaded series of amplifiers as well. Thus, the gain in dB of the cascaded series of amplifiers is log linear with respect to a common control voltage applied to each of the amplifiers of the series.

Abstract: An adaptive laser system (10) incorporates a laser (12) and a novel system and method for determining the slope distribution of a laser beam wavefront. The sensor comprises a ramp filter (16) with a continuous monotonically varying transmittance function and two intensity distribution sensors (18 and 20). Lenses (24, 26 and 28) are provided for focusing and collimating the laser beam as appropriate. A processor (22) calculates the slope distribution from the two intensity distributions obtained by the intensity sensors. The slope calculations can be used to determine commands to predistort the laser beam to approximate a desired flat wavefront at the sensor. The transmittance function of the ramp filter is linear and its spatial width is considerably larger than the expected spreading of the beam due to distorsions in the wavefront. Accordingly, the slope distribution is calculated by pointwise differencing the intensities, normalizing by dividing by the sum of the intensities, and scaling by a factor of one half. Accordingly, a solid state slope sensor which is fast, reliable, economical, and capable of high-resolution evaluations of pulsed as well as continuous wave laser beams is provided.

Abstract: Method and apparatus for automatically and remotely removing unwanted organic films from surfaces of vehicles and satellites in space. A particle beam generator (12) draws molecular oxygen from an on-board supply chamber (14) and develops a stream of positively charged oxygen ions (40). These ions are directed toward a surface or component of a spacecraft such as a solar cell, radiation emission aperture, or sensor objective lens (44) which has been coated by an opacifiying, organic contaminant layer (42) that impairs the efficacy of the spacecraft. The ions (40) bombard the contaminant layer (42) and remove it by both kinetic interaction and chemical oxidation. Spacecraft surfaces and components may be restored and renewed to their original operational capabilities through this method of volatilizing debilitating occluding residues which have been hardened by solar radiation away from the spacecraft as harmless gases (50).
