FDTD modeling of EM field inside microwave cavities

This book deals with the EM analysis of closed microwave cavities based on a three-dimensional FDTD method. The EM analysis is carried out for (i) rectangular microwave ovens and (ii) hybrid-cylindrical microwave autoclaves at 2.45 GHz. The field distribution is first estimated inside domestic rectangular ovens in xy-, yz-, and zx-plane. Further, the RF leakage from the oven door is determined to study the effect of leakage radiation on wireless communication at 2.45 GHz. Furthermore, the EM analysis of the autoclave is carried out based on 3D FDTD using staircase approximation. In order to show the capability of autoclaves (excited with five source) for curing the aerospace components and materials, the field distribution inside autoclave cavity is studied in presence of aerospace samples. The FDTD based modelling of oven and autoclave are explained with the appropriate expressions and illustrations

Auswirkungen von Sommerschnitt und Einsatz von Huminstoffen auf den Nährstoffgehalt der Tafeltraubensorte ‘Alphonse Lavallée’

Viticulture is an important agricultural branch in Turkey. Grape is the most grown fruit species in Turkey. The study was conducted with 'Alphonse Lavallee' grape variety (Vitis vinifera L.) grown on grafted 1103 Paulsen rootstock in Turkey in 2016. In the study effects of Control (C), 1/3 Cluster Tip Reduction (1/3 CTR), Shoot Tip Reduction (STR), Humic Substance Application (HS), 1/3 CTR+ STR, 1/3 CTR+ HS, STR+ HS, 1/3 CTR+ STR+ HS applications on nutritive values were investigated. According to results; the maximum dry matter content 87.64g/100g with HS, 87.76g/100g with 1/3 CTR+ HS, 87.78 with STR+ HS and 87.67 with 1/3 CTR+ STR+ HS applications; the maximum crude protein 3.38g/100g with HS and 3.40g/100g with STR+ HS applications; the maximum crude cellulose 4.46g/100g with HS application; the maximum total sugar content 64.64g/100g with STR and 64.64g/100g with HS applications were obtained. No statistically significant difference was found in terms of crude ash content.Selcuk University, Scientific Research Projects Institute-Turkey [16401100]This research was supported by a grant from Selcuk University, Scientific Research Projects Institute-Turkey (Project No: 16401100)
