چکیده

INTRODUCTION Accurate measurement of dielectric constant and conductivity, also known as, Electrochemical Impedance Spectroscopy (EIS) is a simple, yet powerful technique for analyzing the properties of liquids and gases. EIS is currently used in a wide range of industrial applications including monitoring the purity of boiler water in power plants [1], as well as, the health of lubricants in heavy machinery [2]. Conductivity measurements can also be used as a chemical detector by using a conductivity assay to gain selectivity over specific ions or compounds.

Numerical Modeling and Experimental Study of Probe-Fed Rectangular Dielectric Resonator Antenna (RDRA) Supported by Finite Circular Ground Plane

Dielectric Resonator Antennas (DRAs) have received increased interest in recent years for their potential applications in microwave and millimeter wave communication systems. DRAs are normally used with the support of a ground plane. The radiation and impedance properties therefore depend not only on their physical dimensions and dielectric properties, but also on the size of the ground plane. ...
