“…that in the absence of the sample, in accordance with the simple first order perturbation theory presented in equations (1) and (2). Thus, the filling factor = S / eff quantifies the fraction of the effective volume occupied by the dielectric sample and describes any improvement in field confinement (i.e.…”

Abstract-We present a method of making low loss split-ring resonators for microfluidic sensing at microwave frequencies using silver coated copper wire. We show that a simple geometric modification and the use of square cross-section wire give greater electric field confinement in the capacitive region of the resonant sensor. We use a combination of theoretical analysis, finite element simulations and empirical measurements to demonstrate the subsequent increases in the sensitivity of these split ring resonators for complex permittivity measurements of some common solvents.

“…for investigating the molecular dynamics of materials. The dielectric analysis of pharmaceutical materials (Benoit, 1996) has increased in importance in recent years and is vital to the understanding and application of microwaves to synthetic organic chemistry (Tierney, 2005). Microwave dielectric heating has been very popular since the early 1980s due to the many benefits it offers over conventional heating (Galema, 1997, Gabriel, 1998.…”

“…When a radio wave source at one of the cavity's resonant frequencies is used, the opposing waves generate standing waves, and the cavity stores electromagnetic energy. Material property measurements are needed for a variety of applications in industry, medicine, and pharmaceuticals [1,2]. Chen Saeed et al [7] are studied the complex permittivity characterization of materials within the waveguide cavity resonators.…”

In this paper, the effect of diamond material and silver material as the cavity resonator walls on the resonant frequency has been analyzed. A closed rectangular waveguide can be used as a resonator with a source circuit inside it. The walls of the cavity are made from materials that adequate the dielectric and conductive losses. It is found that the rectangular waveguide frequency resonance decreases with increasing the relative permeability and relative permittivity of diamond and silver. The effect of magnetic susceptibility on the frequency resonant ℓ can be found based on relative permeability where = − 1.
