We propose a plan sentinel prototype consisting of three components. The first component is the development of a plan mining tool which identifies and computes false or missing assumptions and deviations to plans and time phased tasks. The second component, the annotated database, computes plans which the plan mining tool access and parses into a logical annotated rule set. Finally, MAVIS, a to ...

High speed, low cost optical self routing optical crossbar switches with gigabit data rates are key components in optical communication and routing systems. We propose to fabricate and study a monolithically integrated optical crossbar switch which will be inexpensive and high performance. This integrated switch utilizes thin film emitters and detectors integrated directly onto a host integrated c ...

RECENT ADVANCES IN HIGH TEMPERATURE SUPERCONDUCTING (HTSC) THIN FILM TECHNOLOGY ENABLE THE FABRICATION OF LOW-LOSS COMPONENTS THAT WILL IMPROVE THE COST AND PERFORMANCE OF CHANNELIZED RECEIVERS. CHANNELIZED RECEIVERS ARE USED IN SATELLITE TRANSPONDER, ELECTRONIC WARFARE AND ELECTRONICS INTELLIGENCE APPLICATIONS AND ARE COMPRISED OF A GROUP OF NARROW BAND RECEIVERS THAT COVER INDIVIDUAL SLOTS IN A ...

SIGNIFICANT SIMPLIFICATION OF MICROWAVE PHASED ARRAY ANTENNA SYSTEM ARCHITECTURES CAN BE ACHIEVED WITH HTSC DEVICE TECHNOLOGY. ELIMINATION OF THE LOW NOISE AMPLIFIERS (LNAS) CAN BE ACCOMPLISHED THROUGH REPLACEMENT OF THE GAAS PHASE SHIFTERS WITH LOW LOSS HTSC COMPONENTS. A REDUCTION IN COMPLEXITY LOWERS BOTH SYSTEM WEIGHT ANDCOST. KEY TO HTSC TECHNOLOGY INSERTION IN PHASED ARRAY ANTENNAS IS THE DE ...

High quality thin films of high temperature superconductor (HTSC) materials have been grown by a variety of methods. Independent of the growth method, residual stresses in large area HTSC/dielectric multi-layer films, resulting from both thermal expansion and lattice mismatch, continue to be a problem. In Phase I, ATM, working with Dr. Stewart Kurtz of Pennsylvania State University, will calculate ...

The ongoing explosion of microwave radar and communications systems calls for improvement in electronically scanned antennas (ESAs). However, current ESAs crafted from multiple individual elements are extremely expensive. Forming an antenna with integrated scanning and impedance matching elements on a single substrate using thin film technologies may decrease costs by up to two orders of magnitu ...

This Phase I project has two primary objectives. The first objective is to develop an engineering model of Resonant Tunneling Devices (RTD) to be implemented in AIM-Spice, a commercial software package running under Windows 95/NT. The development of a reliable device model is a prerequisite for the design and production of any semiconductor device technology. The RTD model will be a semi-empiri ...

IT IS COMMONLY AGREED THAT THE DEVELOPMENT OF ULTRA-HIGH DENSITY AND VERY HIGH SPEED ELECTRONICS FOR COMPUTING AND SIGNAL PROCESSING IS PRESENTLY LIMITED NOT BY THE CIRCUT COMPONENTS THEMSELVES BUT RATHER BY THE ELECTRONIC PACKAGING. HIGH-TEMPERATURE SUPERCONDUCTOR (HTSC) FILMS ARE EXPECTED TO MAKE A SIGNIFICANT IMPACT ON THIS TECHNOLOGY FOR HIGH PERFORMANCE APPLICATIONS IF A NUMBER OF CRITICAL MA ...
