Abstract:
The present invention describes nano-scale fabrication technique used to create a sub- micron wide gap across the center conductor of a coplanar waveguide transmission line configured in a fixed-fixed beam arrangement, resulting in a pair of opposing cantilever beams that comprise an electro-mechanical switch. Accordingly, a nanometer-scale mechanical switch with very high switching speed and low actuation voltage has been developed. This switch is intended primarily for application in the RF/microwave/wireless industry.
Abstract:
The invention is a microminiature wireless environmental sensor (10) that has integrated both sensor and transmitter functions into one function. The basic operating principle for the device is that variable components of an RF circuit (10) can be interfaced to the outside world environmental signals resulting in proportional changes in the transmission characteristics or transmission of data/bits from the RF transmitter circuit. This utilization of environmental sensitive variable elements within a wireless transceiver circuit permits the fusion of both sensor and communications function into an integrated single function.
Abstract:
In accordance with the present invention, novel superparamagnetic magneto-dielectric polymer nanocomposites are synthesized using a novel process. The tunability of the dielectric/magnetic properties demonstrated by this novel polymer nanocomposite, when an external DC magnetic field is applied, exceeds what has been previously reported for magneto-dielectric polymer nanocomposite materials.
Abstract:
The present invention provides a monolithic inductor developed using radio frequency micro electromechanical (RF MENS) techniques. In a particular embodiment of the present invention, a tunable radio frequency micro electromechanical inductor includes a coplanar waveguide and at least one direct current actuatable contact switch positioned to vary the effective width of a narrow inductive section of the center conductor of the CPW line upon actuation the DC contact switch.
