A methodology is proposed for introducing the capability of modeling active MMICs into the industry-standard three dimensional electromagnetic field simulator High Frequency Structure Simulator (HFSS) and Maxwell SI Eminence. The first objective of the proposed work is to evaluate the existing capabilities of HFSS/Eminence for characterizing the passive three dimensional interconnect problems as ...

Currently, most antenna array designs are mechanically steered. However, as demand for higher performance antennas increases, an electronic replacement for the mechanical system becomes necessary. An alternative that may prove to be more cost effective is to use ferrite patch antennas as the elements in the array. The antenna's radiation characteristics are controlled by the direction and magni ...

We propose a unique GaN-Al(sub x)Ga(sub 1-x)N heterojunction based CCD for imaging in the ultraviolet (wavelengths less than 365 nm). Our proposed device will be solid state, TTL compatible and in it's final configuration solar blind. The Phase I program is aimed at establishing the technical feasibility of our device concept. Our proposed CCD is in essence a GaN-AlGaN gated photoconductor with ...

This proposal describes new low cost, low risk semiconductor-based approaches to fuze trigger circuit technology. These innovative approaches build on the promising new technology platform developed by ARIA as part of earlier SBIR research. ARIA's technology platform, initially developed for driving extremely high speed (400 picosecond rise time), high peak current pulses (400A) through laser di ...

A concept for intelligent, multimedia computer-based training systems integrating intelligent agents with eye tracking and speech (ScanEval) is presented as a means of developing training systems that are more responsive, engaging, and motivating to trainees than current systems relying on more traditional user interface and pedagogical sequencing mechanisms. It is argued, based on published rese ...

This effort will address five problems in the process design of heterojunction bipolar transistors (HBTs) and high electron mobility transistors (HEMTs): (1) HEMT thermal impedances will be measured using a novel method and will be compared with finite-element simulations to provide more accurate values for computer-aided design programs. (2) The role of the spacer layer in HEMT performance and ...

Increasingly fast networks, the maturity of agent-oriented and expert systems, and the growing popularity of distributed computing via the Internet have made the attack on enemy information systems highly feasible. Since 1992, Intelligent Investments personnel have been considering several innovative methods for applying these technologies to examine the security of systems. We propose ...
