The study of single phase diode rectifiers with high power factor and low total harmonic distortion
(University of Missouri--Columbia, 2008)
The mains current in an ac/dc converter contains periodic current pulses due to the action of rectifier and output filter capacitor. The high current peaks cause harmonic distortion of the supply current and low power ...
A TEM cell design to study electromagnetic radiation exposure from cellular phones
(University of Missouri--Columbia, 2008)
A transverse electromagnetic (TEM) cell was designed and fitted with a double ended monopole antenna as a signal leader in order to couple electromagnetic radiation from GSM 900 and 1800 commercial cellular phones into a ...
Effect of gate length in enhancing current in a silicon nanowire wrap around gate MOSFET
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] A 3-D silicon nanowire wrap around gate (WAG) MOSFET was designed and it was shown that the properties of the cylindrical channel silicon nanowire ...
Silicon carbide as a photoconductive switch material for high power applications

Optimization of charge collection efficiency in MSM photodetector
(University of Missouri--Columbia, 2005)
The effects of different geometries, heights and concentrations per unit area of gratings in the active region of a metal semiconductor metal photo-detector have been analyzed for enhanced charge collection through ...
Charge collection mechanisms in a sub-micron grated MSM photodector: field analysis
(University of Missouri--Columbia, 2005)
Enhanced charge collection mechanisms due to sub-micron wall-like silicon structures on the active surface of a metal-semiconductor-metal (MSM) photodetector were studied through the analysis of transmitted electromagnetic ...
Near field microwave imaging techniques for embedded object detection and shape reconstruction
(University of Missouri--Columbia, 2007)
A method for the detection, imaging and reconstruction of an embedded object through the application of a near field, frequency-synthesized microwave pulse is described. The work describes an alternate detection and ...
Electromagnetic effects on soybeans
(University of Missouri--Columbia, 2007)
In this study we have exposed different varieties of soybean seeds to electromagnetic (EM) radiation at a frequency other than that of light. The objective was to determine changes in the germination rate, if any, under ...
Design and construction of helmholtz coil for biomagnetic studies on soybean
(University of Missouri--Columbia, 2008)
A Helmholtz coil with a large usable area of uniform field was designed, constructed and characterized, specifically for bioelectric studies. The design and analysis of the coil were carried out through experiments and the ...
