CLEVELAND, Oct. 3 /PRNewswire/ -- Teraphysics Corporation has received
a $100,000 Phase I Small Business Technology Transfer contract from the Air
Force Office of Scientific Research for the development of a miniature 95
gigahertz amplifier for high power radar and communications applications.
In collaboration with RTI-International of Research Triangle Park,
North Carolina, Teraphysics will employ state of the art microfabrication
technology in the development of a diamond studded micro helix traveling
wave tube (TWT). The device will be designed by Teraphysics adapting
technology previously patented by the company. Fabrication experiments to
establish the feasibility of the design will be conducted at RTI and the
Teraphysics facility in Cleveland.
"This contract is intended not only to develop an amplifier with a wide
range of military and commercial applications, but to explore the
applicability of fabrication techniques that have not previously been
utilized in this technical area," said Dr. Jim Dayton, chief technology
officer for Teraphysics and principal investigator on the contract.
Teraphysics primarily develops compact and efficient devices that
operate in or near the terahertz band, the only commercially untapped
portion of the electro-magnetic spectrum. The company has engineered the
world's first palm- sized signal source operating in the valuable terahertz
frequency range capable of broad commercial and military applications.
The company has received 12 development contracts from seven government
agencies for total federal funding of $4 million since August 2002. Four
are SBIR Phase II contracts.
The Air Force wants to develop a new class of miniature high power
transmitters for operation at 95 gigahertz. At the same time, they seek to
apply to vacuum electronics the manufacturing opportunities offered by
microfabrication technology initially developed for other areas.
Dayton and the Teraphysics team will develop the novel 95 gigahertz
traveling wave tube by combining proven computer aided design techniques,
the company's proprietary application of nanotechnology for
laboratory-grown diamond and RTI's microfabrication expertise.
The typical TWT, used in nearly all microwave and millimeter wave
transmitters, has a helical wire coil supported within a metal barrel by
ceramic rods. However, conventional fabrication techniques have limited the
helical TWT performance range to less than 60 gigahertz. To achieve 95
gigahertz in this device, the ceramic rods will be replaced by diamond
studs and the helix will be fabricated using novel lithographic techniques
rather than winding a metal wire around a mandrel.
ABOUT THE COMPANY
Teraphysics Corporation, a Cleveland, Ohio-based company, develops
devices that operate in millimeter frequencies and the sub-millimeter
terahertz band, the only commercially untapped portion of the
electro-magnetic spectrum. The company has engineered the world's first
palm-sized terahertz signal source capable of broad application for
operation in this coveted frequency range. Teraphysics is part of Genvac
Holdings, a privately-held company.
