MSM photodiode as the switching element in a photoswitch-based class E microwave power amplifier
(University of Missouri--Columbia, 2008)
A photoswitch is designed for use as the switching element in a 2 GHz class E amplifier. The application of this amplifier is as the final-stage amplifier in the transmit-receive module of a phased-array radar system. The ...
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 ...
Modeling the behavior of a homopolar motor
(University of Missouri--Columbia, 2008)
The design, construction, and operating characteristics of a homopolar motor are described in this thesis using both physical experimentation and simulation software. This type of motor converts electrical energy into ...
Cognitive radios: spectrum sensing issues
(University of Missouri--Columbia, 2007)
Cognitive Radio can smartly sense and adapts with the changing environment by altering its transmitting parameters, such as modulation, frequency, frame format etc. The main challenges with cognitive radios are that it ...
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 ...
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 ...
Optically triggered thyristor for capacitor discharge applications
