GA --- February 13, 2006 --- nGimat Co. announced
today the recent issuances of two U.S. patents (Nos.
6,975,500 and 6,986,955) as well as a foreign patent
(GB2411661). These patents cover fundamental compositions
of matter and methods as well as new tunable capacitors
for nGimat-designed components expected to be used
in commercial and military wireless equipment. Such
components include tunable filters and phase shifters.
These components are designed to allow future homeland
security communications handsets to tune to multiple
frequency bands as well as provide increased security
of transmitted signals by beam direction. In addition,
these components are anticipated to be substantially
less expensive than what is currently being produced.
nGimat's U.S. Patent No. 6,986,955, entitled “Electronic and Optical Materials,” is
directed to thin films of barium strontium titanate deposited on a sapphire
substrate, including C-plane sapphire. The crystalline structure of the thin
films is epitaxial or near-epitaxial. Barium strontium titanate (“BST”) has
properties that are particularly suitable for a variety of electronic and optical
applications. Significantly, properties, such as refractive index and dielectric
constant, of BST are tunable by application of a biasing electrical field.
The very thin films of the invention have important promise for miniaturized
electronic and electrooptical devices.
nGimat's US Patent No. 6,975,500, entitled “Capacitor Having Improved Electrodes,” is
directed to multi-layer tunable capacitors of specific configuration, including
several layers. They are formed from dielectric material that has one or more
discrete electrodes, each electrode being exposed to at least two thicknesses.
These electrodes are surrounded by wider insulative material such that the
material can be patterned into capacitors having specific values. The thin
dielectric can be a tunable material so that the capacitance can be varied
by adding thin electrodes that interact with direct current.
nGimat's British Patent No. GB 2 411 611, entitled “Variable Capacitors, Composite
Materials,” is directed to materials used in forming variable capacitors that
can be tuned by a biasing voltage. The variable capacitors are formed from
novel nanoparticles and composite materials. The invention is a method of producing
nanoparticulates of elemental metal as well as a method of depositing at least
a monolayer of metal nanoparticles on a substrate.
nGimat Co. is a cost-effective manufacturer and innovator of engineered nanomaterials
in the following areas: nanopowders, thin films and devices. nGimat's Combustion
Chemical Vapor Deposition (CCVD) and NanoSpraySM Processes along with its
Nanomiser® Device enable synthesis of nanoparticles and thin films.
