Millimeter-wave circuit design requires accurate models to optimize performance, to minimize the number of preliminary designs, and to allow design centering for uniformity and high yield reducing cost and improving reliability. Existing bipolar circuit models fail at prediction of high frequency, non-linear, and switching behaviors. These models are not specified by the physical structure of the ...

The recent FCC allocation of the frequency band 27.5 to 29.5 GHz band for cellular broadcast television provides a critical opportunity for the demonstration of quasi-optical transmitter technology. We are proposing a new millimeter wave quasi-optical spatial power combiner for this application. The combiner utilizes the concept of millimeter wave mode-locking, developed by Avoca researchers, to t ...

PROJECT SUMMARY: A novel chemistry is proposed for solder mask coatings on printed circuit boards (PCBs). This chemistry permits 100% solids application, eliminating objectionable solvents. The innovative chemistry uses a hardener blocked with a reactive component. This hardener is added to suitable monomers and oligomers containing acid (COOH) functionality along with photosensitizers and photoin ...

AN OPTICAL RELAY USED TO IMAGE TEXT, GRAPHICS, AND VIDEO IN A HEAD MOUNTED DISPLAY (HMD) SYSTEM IS PROPOSED. COMPUTER GENERATED HOLOGRAMS WILL BE EMPLOYED IN CONJUNCTION WITH CONVENTIONAL-REFRACTIVE OPTICS IN ORDER TO REDUCE THE WEIGHT AND SIZE OF THE SYSTEM WHILE ENHANCING ITS PERFORMANCE. BOTH LIQUID CRYSTAL DISPLAYS (LCD) AND DEFORMABLE MIRROR DEVICES (DMD) ILLUMINATED BY A LOW POWER LASER DIOD ...

COMPOSITE MATERIALS HAVE ADVANTAGES FOR ROCKET MOTOR CASES: LIGHTWEIGHT, HIGH STRENGTH, AND FAVORABLE 'INSENSITIVE MUNITIONS' BEHAVIOR. WET BRAIDIIG OFFERS ECONOMIC ADVANTAGES OVER FILAMENT WINDING FOR THE PRODUCTION OF COMPOSITE CASES. HOWEVER, THERE ARE SEVERAL AREAS IN WHICH IMPROVEMENTS IN THE STRUCTURAL EFFICIENCY OF BRAIDED ROCKET MOTOR CASES ARE NEEDED TO MATCH THE STRUCTURAL EFFICIENCY OF ...

In this Applied/Exploratory Development program we will develop a new field emitter based optoelectric module which will be initially evaluated as a digital photographic printer head (light source array). This optical printer head concept provides the opportunity for a low cost, low spatial volume, low energy consumption, and high resolution printed image generator. A major US camera manufacturer ...

Field emitter based devices offer exciting theoretical performance capabilities such as temperature insensitivity, high frequency, high current density, high efficiencies, and small size. Efforts to demonstrate these capabilities and apply them have been held back by the fabrication methods that are currently available. Most of these methods cannot, among other limitations, reliably provide struct ...

In this Applied/Exploratory Development program we will determine feasibility of the use of a new CCD driver concept for matrix addressed field emitter array (FEA) displays which has been under development at the Rochester Institute of Technology. This new serial driver concept, with its unique gray level storage and transfer capability, provides the opportunity for a low cost, low spatial volume, ...
