Topology Optimization And Cooling System Design For Functionally Graded Patch Antenna Substrates

This project was also a part of my master thesis. It was focused on topology optimization, finite element analysis, patch antennas and functionally graded material manufacturing. I applied topology optimization techniques on patch antenna structure using different composite material subdomains. In that study the key point was to obtain a unique structure which represents the best performance under deserved objectives subject to several constraints. By doing this, I dealt with heuristic optimization techniques by particularly using the genetic algorithm involving the loop of FEA simulations.

In addition, I designed and experimented a cooling device in order to manufacture functionally graded antenna substrate by manipulating microporous structure. As a result my thesis work, two papers were accepted for APS/URSI 2017 conference.

Thesis Abstract

 


Resonance frequency analysis of MEMS based on piezoelectric micro-cantilever beam for vibration energy harvesting applications

The aim of the project was to investigate the geometrical effects on the resonance frequency of unimorph layered cantilever by using finite element analysis (FEA). This project was supported by the Scientific and Technological Research Council of Turkey (TUBITAK 2209/A). The output of this work was presented as  poster in the 10th Nanoscience and Nanotechnology Conference in 2014, Istanbul.

I was a visiting researcher in Professor Steve Bull’s research group at Newcastle University, UK. I took part in the mechanical test of titanium and cobalt chrome materials as well as the analysis of the experiment data. A journal article on this study was published in Thin Solid Films.
