Abstract

The main purpose of this study is evaluation of temperature (20-80 °C) and frequency (1 MHz -1 GHz) dependent dielectric properties of vegetable oils by simulation (CST Microwave Studio). In order to accomplish this task a probe is mathematically characterized and tested with three different pure liquids with well-known dielectric properties.A mathematical model of the probe reflection coefficient is derived combining TL theory and known circuit parameters of the coaxial cable. The only variables in the mathematical model are the Cole-Cole parameters. The Cole-Cole parameters of any liquid/oil are obtained by fitting of the measured reflection coefficient from simulation with the mathematical model

Özet

Bu çalışmanın ana amacı bitkisel yağların sıcaklığa (20-80°C) ve frekansa (1 MHz-1 GHz) bağlı dielektrik özelliklerinin benzetim yoluyla (CST Microwave Studio) değerlendirilmesidir. Bu görevi yerine getirmek için bir prob matematiksel olarak karakterize edildi ve iyi bilinen dielektrik özelliklere sahip üç farklı saf sıvı ile test edildi. Probun yansıma katsayısının bir matematiksel modeli iletim hattı teorisi ve koaksiyel kablonun bilinen devre parametrelerini birleştirerek elde edildi. Matematiksel modeldeki tek değişkenler Cole-Cole parametrelerdir. Herhangi bir sıvının Cole-Cole parametreleri matematiksel modeli ile benzetim programından ölçülen yansıma katsayısına yaklaştırılarak elde edilir
