Microwave Dielectric Measurement of Solids and Liquids over 1 to 4 Ghz Using Transmission Line Technique and Coaxial Cavity
Accurate microwave dielectric measurement of materials is necessary data for the design engineer during the development stage of electronic and communication components. Several techniques have been published in recent years for measurement of dielectric properties of materials at microwave frequencies. Each of these techniques has some limitations in terms of accuracy and frequency coverage. T...
متن کاملRadiation From a Dielectric Coated Hemi spherical Conductor Fed by a Coaxial Transmission Line
Abstruct-A dielectric coated hemispherical conductor mounted on an infinite perfectly conducting ground plane and fed by a coaxial transmission line is investigated. Green's functions for the region above the ground plane are derived with separated homogeneous and particular solution parts so as to be compatible with numerical analysis techniques. A magnetic field integral equation is construct...
متن کاملA 2.5 Gigawatt Liquid Dielectric Coaxial Pulse Forming Line
The pulse forming line (PFL) can store approximately 600 joules at 100 kilovolts. Line impedance is 0.86 ohm and discharge time into a matched load is 200 nanoseconds. The coaxial line is filled with a mixture of 60% ethylene glycol and 40% water, by weight, yielding the maximum freezing point depression. The dielectric liquid is dearated, deionized and cooled to subzero temperature in order to...
متن کاملThe Measurement of Dielectric Properties of Liquids at Microwave Frequencies Using Open-ended Coaxial Probes
Significant progress has been made in recent years in the development of microwave tomographic imaging systems for medical applications. In order to design an appropriate microwave imaging system for industrial applications, and to interpret the images produced, the materials under imaging need to be characterised. In this paper, we describe the use of open-ended coaxial probes for the measurem...
