Design and analysis of ultrashort femtosecond laser amplifiers
Doğan, Ersin; Bilikmen, Kadri Sinan; Department of Physics (2006)
This thesis presents a compact femtosecond laser amplifier design for optical preamplifiers and power amplifiers consist of theoretical perspective, simulations to analyze and optimize beam performance. The propagation through optical media is simulated for every optical component such as mirrors and nonlinear crystal separately and suggested realignment of these components required increasing amplifier performance. Finally Gaussian beam propagation and aberration compensation has been conducted.
Design and implementation of an interface circuit for piezoelectric energy harvesters
Chamanian, Salar; Külah, Haluk; Muhtaroğlu, Ali; Department of Electrical and Electronics Engineering (2018)
Micro-fabricated piezoelectric transducer is a prominent harvesting method due to its small size and relatively high energy density. However, the available interface circuits (IC) in the literature for piezoelectric energy harvesters (PEH) are generally designed for macro-scaled versions having a power output in the range of hundreds µW. The efficiency of such systems is significantly diminished when input power drops to tens of µWs or less, which is the pertinent power output range for micro-fabricated dev...
Design and analysis of a high voltage exploding foil initiator for missile systems
Yılmaz, Muhammed Yusuf; Ulaş, Abdullah; Department of Mechanical Engineering (2013)
Increasing insensitivity demands on designing and producing munitions necessitates utilizing primarily insensitive initiation trains specifically in missile systems. Exploding Foil Initiator (EFI) is a high voltage detonator that is used as the initiation elementof rocket motor and warhead initiation trains of modern insensitive missile systems. In this thesis, EFI prototypes are designed and manufactured with the knowledge gained from detailed literature studies. An experimental setup is constructed includ...
Design and Analysis of PLLs for Line-connected Converters in Three Phase Systems
Vyawahare, D.; Kose, H.; AYDEMİR, MEHMET TİMUR; Chandorkar, M. C. (2011-09-10)
This paper is concerned with phase locked loop (PLL) structures for use in the control of line connected power electronic converters in three phase systems. Such converters have to operate under conditions in which the power system phase voltages are often unbalanced. The unbalanced and distorted line voltage vector as observed in the stationary reference frame generally has instantaneous rates of change components in the radial as well as in the angular directions. The essential task of a PLL in this conte...
Design and Analysis of Nanoantenna Arrays for Imaging and Sensing Applications at Optical Frequencies
Isiklar, Goktug; Cetin, Isa Can; Algun, Mustafa; Ergül, Özgür Salih (2019-01-01)
We present computational analysis of nanoantenna arrays for imaging and sensing applications at optical frequencies. Arrays of metallic nanoantennas are considered in an accurate simulation environment based on surface integral equations and the multilevel fast multipole algorithm developed for plasmonic structures. Near-zone responses of the designed arrays to nearby nanoparticles are investigated in detail to demonstrate the feasibility of detection. We show that both metallic and dielectric nanoparticles...
