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 ...
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 ...
Broadband beamforming and direction finding using concentric ring array
(University of Missouri--Columbia, 2005)
Sensor arrays have been used widely in applications including radar, sonar, seismology, biomedicine, communications and imaging. A very popular type of sensor array is circular array, which has almost invariant array pattern ...
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 ...
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 ...
Moving object localization using frequency measurements
(University of Missouri--Columbia, 2021)
This research investigates the ability of locating a moving object using the Doppler shifts of a carrier frequency signal sent or re ected by the object and observed by several fixed or moving sensors spatially distributed ...
