Towards Cconstruction Of Reliable Molecular-Based Electronic Devices
Dr. Shachar Richter
Tel-Aviv University
*************************
Molecular electronics allows the implementation of a small array of molecules as the fundamental unit for the future nano-electronic devices. In this new field, the goal is to replace a wire, transistor or other basic solid-state electronic components, with a set of functional molecules that perform semiconductor nano-scale devices in an integrated circuit.
In this research we present a new hybrid vertical device, suitable for reproducible 1-V measurements of organic and biological molecules deposited in a Self ASsembly technique. The device is constructed by vertical architecture, which leads to a creation of area of "standing" molecules, completely encapsulated between two metal electrodes. Several examples of such devices would be presented.

Imaging Phased Array Radar at Low Cost, for Mary and Commercial Application

**************************
Introduction
Available imaging sensors are all limited in performances: video cameras can work only with light, infrared and laser sensors cannot work in foggy, smoky or heavily dusty environments. The only imaging device able to work in any possible scenario is the Imaging Radar, based on A0tive Phased Array Antenna. This system is known, and is used for military purposes. Because of the high cost of its many T/R modules, its application is limited.
New Technology for Affordable Imaging Radar
ABACUS MW ltd has patented a new technology for producing a distributed T/R module at low cost. The real estate of the semiconductor used for fabricating the MMIC components is 40% lower than any conventional T/R module. The mainframe of the radar results smaller lighter and cheaper. Using a planar antenna based on patch radiators, even the expensive circulators can be eliminated.
Description of The New T/R Module Technology
The core element of the new system is a chain of Injected Push-Push Oscillators, used with several unprecedented (and patented), functionalities: 1). they perform distributed phase shift of the signal, 2). multiply the frequency of the master reference signal, 3). and amplify the power of the processed signal.
Possible Military and Commercial Applications
Small, low cost active phased array radars can solve visibility problems to military vehicles, operating in smoky or sandy environment; can implement automatic driving in commercial vehicles; can perform effective border surveillance. Large, low cost active phased array antennas can fulfill the needs of a modern fleet, as requested by the US Navy.
