This thesis involves modeling of an electromagnetic launcher (EML) by taking all of the variables that affect the system performance into consideration. The study includes deriving related electrical and kinematic equations and developing models based on these equations. Two models are built in different simulation programs to be able to analyze the system from different aspects. Models are verified by means of experimental results. An experimental setup is designed and implemented to represent a similar behavior to EML. The same system is simulated using two simulation models. Experimental and simulation results are compared and discussed.

Hybrid CFIE-EFIE solution of composite geometries with coexisting open and closed surfaces
Ergül, Özgür Salih (2005-07-08)
The combined-field integral equation (CFIE) is employed to formulate the electromagnetic scattering and radiation problems of composite geometries with coexisting open and closed conducting surfaces. Conventional formulations of these problems with the electric-field integral equation (EFIE) lead to inefficient solutions due to the ill-conditioning of the matrix equations and the internal-resonance problems. The hybrid CFIE-EFIE technique introduced in this paper, based on the application of the CRE on the ...
Software metamaterials: Transformation media based multi-scale techniques for computational electromagnetics
Ozgun, Ozlem; Kuzuoğlu, Mustafa (2013-03-01)
This paper presents computational models employing special transformation-based media-which we call software metamaterials-for the purpose of enhancing the ability of numerical modeling methods for solving multi-scale electromagnetic boundary value problems involving features with multiple length or frequency scales or both. The multi-scale problems, in general, suffer from difficulties in mesh generation and the number of unknowns due to certain meshing requirements dictated by the fine features of the pro...
Fast and accurate solutions of large-scale scattering problems with parallel multilevel fast multipole algorithm
Ergül, Özgür Salih (2007-06-15)
Fast and accurate solution of large-scale scattering problems obtained by integral-equation formulations for conducting surfaces is considered in this paper. By employing a parallel implementation of the multilevel fast multipole algorithm (MLFMA) on relatively inexpensive platforms. Specifically, the solution of a scattering problem with 33,791,232 unknowns, which is even larger than the 20-million unknown problem reported recently. Indeed, this 33-million-unknown problem is the largest integral-equation p...
Correction of temperature and acceleration effects on MEMS gyro output signals /
Ali, Muhammad; Akın, Tayfun; Azgın, Kıvanç; Department of Electrical and Electronics Engineering (2014)
The scope of this thesis is to study the effects of temperature and acceleration on a MEMS gyroscope and present a workable solution to compensate these errors using various techniques. Compensation for errors is implemented considering the output bias data of the gyroscope. The study also provides comparison of these various techniques, namely Polynomial Curve fitting and Neural Networks. In addition, Moving Average Filtering is used as an auxiliary technique. The study provides novelty of compensating bot...
Analysis of Lossy Dielectric Objects with the Multilevel Fast Multipole Algorithm
Ergül, Özgür Salih (2011-07-08)
Rigorous solutions of electromagnetics problems involving lossy dielectric objects are considered. Problems are formulated with two recently developed formulations, namely, the combined-tangential formulation (CTF) and the electric and magnetic current combined-field integral equation (JMCFIE), and solved iteratively using the multilevel fast multipole algorithm (MLFMA). Accuracy and efficiency of solutions are compared for different objects and conductivity values. We show that iterative solutions of CTF a...
