Microwave Cavity Resonator Based Dielectric Constants Measurement of Non-magnetic Solid Materials Dr. Jasmine Saini (Author-1) Department of ECE Jaypee Institute of Information Technology, Noida Brajesh Kumar Dixit (Author-2) Department of ECE Jaypee Institute of Information Technology, Noida Abstract--In this paper, the importance of measuring dielectric properties of solid materials is discussed, which is of great significance in the fields of biological and agriculture science. The analysis and simulation of the solid materials is done by employing a hollow cylindrical cavity resonator. This method provides parameters of high accuracy for calculating the permittivity and permeability of solid materials. The dielectric properties of hollow cavity are first determined by measuring resonant frequency and quality factor. Then, the same analysis has been carried out by…show more content…
New artificial materials called meta-materials have some interesting electromagnetic characteristics that is not found in nature. One of the characteristics is the negative index of refraction which is realized by combining negative permittivity and permeability. These negative permittivity and permeability are commonly realized by split ring resonators (SRRs). Here, a mathematical formulation is adopted for analytical derivation of dielectric constants of non-magnetic solid materials. For this, the geometry of cylindrical single split ring resonator is defined with the parameters like inner radius (R), thickness (w), height (h), and gap width (g). The sub-wavelength split ring resonator is characterized by inductance (L) and capacitance (C). The geometry of split ring resonator with designing parameters is shown in the Fig.
