Oil Quality Monitoring in Gasoline Spark Ignition Engine Using Oil Dielectric Measurement
Oil analysis is one of the main methods for monitoring the status of internal combustion engines and oils to ensure the lubricant's protective performance and engine health. This paper investigate oil condition monitoring in gasoline engine using oil dielectric coefficient measurement. At first capacitive sensor pectinate type is designed and manufactured that engine oil can pass through the se...
متن کاملMeasurement of Dielectric Constant and Loss Factor of the Dielectric Material at Microwave Frequencies
A new technique to evaluate the dielectric constant and loss factor of a homogeneous dielectric material using rectangular shaped perturb cavity has been developed. The values of S-parameters are measured experimentally by placing the sample in the center of the cavity resonator. Sample under test is fabricated in the form of a cylinder. The real and imaginary part of the permittivity can be th...
متن کاملAccurate Analysis of Dielectric Backed Planar Conducting Layers of Arbitrarily Shaped in a Rectangular Waveguide
The characteristics of dielectric backed planar conducting layers of arbitrarily shaped in a rectangular waveguide are calculated by means of coupled integral equation technique (CIET) which accurately takes higher order mode interactions. Equivalent structures for the accurate analysis whole structure are introduced in which magnetic surface currents are identified as the unknowns at the apert...
متن کاملField analysis of a dielectric-loaded rectangular waveguide accelerating structure.
Recently, there has been some interest in planar or rectangular dielectric accelerating structures for future high-gradient linear accelerators. In this paper, we present a detailed analysis of the modes of a dielectric-loaded rectangular waveguide accelerating structure based on a circuit model approximation and mode matching method. In general, the acceleration field in a synchronous accelera...
متن کاملAnalysis of Inductive Dielectric Posts in Rectangular Waveguide
A rapidly converging moment solution for the complete analysis of homogeneous dielectric posts of the inductive type in rectangular waveguide is presented. The moment method approach uses filamentary currents to simulate both the field scattered by the post and the field inside the post and in turn point-matches the continuity conditions for the tangential components of the electric and magneti...
