Effects of nano-second pulsed electric fields (nsPEF) on human prostate cancer cell line - LNCaP
(University of Missouri--Columbia, 2008)
The effects of Pulsed Electric Fields have been a period of study since past few decades, which was mainly on the electroporation, bacterial decontamination and biofouling. But the development of technology to produce ...
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 ...
Simulation algorithms for fractal radiation
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This thesis presents a method to analyze a series of structures, referred to as fractals, that radiate electromagnetic waves. The fractal series are ...
Optimizing antenna gain with a metamaterial filter
(University of Missouri--Columbia, 2011)
Metamaterials are man-made structures, usually designed by placing electromagnetic resonators, such as split ring resonators (SRRs), in a periodic array. Metamaterials also exhibit lensing properties, and, when placed next ...
Effects of nano-second pulsed electric fields on human breast cancer cell line-MCF7
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Effects of nanosecond pulsed electric fields on the human breast cancer cell line MCF-7 have been investigated for changes in cell number, DNA ...
Effects of front and bottom texturings on gallium arsenide solar cell characteristics
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The Gallium Arsenide solar cells are of particular interest in many applications due to its advantages over silicon. Its high absorptivity requires a ...
Maximizing terahertz pulse amplitude from low temperature gallium arsenide photo conductive semiconductor switch
(University of Missouri--Columbia, 2011)
A signal is produced by the photoconductive action in a PCSS, which travels through the bulk to the metallic contacts and is radiated through the electrodes of the PCSS. The simulation analysis was done for the semiconductor ...
Case study of normal and high glucose laden cell response to cellular phone radiation using GTEM cell
(University of Missouri--Columbia, 2012)
The primary objective of this dissertation is twofold. First, to study the response of red and white blood cell and normal and high glucose blood to cellular phone radiation exposures at frequencies of 850 and 900 MHz. ...
Comparison of substrate conditions in low-temperature gallium arsenide and semi-insulating gallium arsenide during terahertz pulse generation
(University of Missouri--Columbia, 2011)
The use of GaAs photoconductive semiconductor switches (PCSS) for generating THz radiation is well known. Both semi-insulating (SI) and Low-temperature (LT) grown Gallium Arsenide (GaAs) have been used. In this research ...
Characterizing carrier transport in silicon thin film metal semiconductor metal structures
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Due to its operational simplicity and ease of fabrication, metal semiconductor metal thin film structures have been the focus of attention for many ...
Comparative study of ballistic transport in Si and GaAs using non equilibrium Green's function formalism
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The simulation study presented in this research has two basic objectives. The first objective is to establish a consistency in the results for quantum ...
Design and analysis of reconfigurable phased array antenna for wireless local area network applications
(University of Missouri--Columbia, 2014)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.]
Asymmetric quantum well structures for enhanced infrared photon absorption
(University of Missouri--Columbia, 2013)
Compared to inter-band transition for photon absorption in a quantum wells, intra-band (or inter-subband) transitions in heterojunction (GaAs/InP) quantum wells can provide access to a broader range of wavelengths for ...
