Automated Measurement of Complex Permeability and Permittivity at High Frequencies
The paper reports here on the reflection frequency-domain measurements to determine the selected electromagnetic properties of materials using an Agilent 8714ET Network analyzer. The measurement process as well as results evaluation are performed by means of computer control. For this purpose, a VEE program (Agilent technology) has been developed. The discussion concerning the optimisation of m...
متن کاملModeling-assisted Perturbation Technique for Measurement of Complex Permittivity
Basic assumption and accuracy of complex permittivity measurement by perturbation technique are proposed to be verified by FDTD simulation of experimental cavity with QuickWave-3D. Determination of dielectric constant and loss factor of a piece of wet movie-film in rectangular resonator is shown to be very sensitive to film position and approved to be valid for low contents of water.
متن کاملWide-band Rock and Ore Samples Complex Permittivity Measurement
Ground penetrating radar (GPR) is based on high-frequency electromagnetic wave propagation and its detecting targets are below the ground surface (Daniels, 2004; Jol, 2009). Velocity and attenuation are two important factors describing the electromagnetic wave in the media composed of rocks or soils. Velocity is inverse proportional to the root of the permittivity while other parameters are fix...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولBiological Applications of a Technique for Broadband Complex Permittivity Measurements
A broadband coax technique developed by us for the measurement of dielectric properties of biological substances upto at least 20 GHz, is discussed. For water-based materials such as blood or muscle substitute phantoms, a 0.047 inch size probe is essential to minimize errors due to radiation. The data indicate the importance of the dielectric volume of the constituents, and enable tailoring of ...
