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 ...

The objective of the proposed effort is to design an all solid-state, eye-safe (1.5 um) laser that will abe superior to existing eye-safe lasers in terms of power, efficiency, cost, and beam quality. The proposed laser system is based on solid-state Raman shifting of Nd:YAG laser radiation using barium nitrate. Several designs will be presented and performance characteristics (based on properties ...

Recent technological advancements in the growth of bulk single crystal, ternary, III-V alloys strongly indicate the potential for commercial feasibility of these alloy substrates. Commercial availability will permit realization of the concept of substrate engineering. Based on reported developments in the (In,Ga)As and (In,Ga)Sb ternary systems, we propose to develop a materials technology for t ...

We propose to develop a novel technology for fabricating high speed integrated photoreceiver MMIC chips on the InP substrate. The in- novation consists of a new, unique, optically resonant, high speed InO.53GaO.47As photodetector that has a wavelength selective response. This resonant detector not only has improved quantum efficiency over conventional InGaAs high speed photodetectors, but also dis ...

A solution to the problem of interchip interconnects is proposed that employs electro-optical links implemented monolithically on silicon substrates. This approach addresses the fundamental material incompatibility problem of opto-electronics by implementing electronics in silicon and optical components using III-V compounds on a single chip. This is made possible through the use of "selective e ...
