Uniqueness of Complex Permittivity Reconstruction in a Parallel-Plane Waveguide
[1] The paper presents a statement and a proof of uniqueness of solution to the inverse problem of determination of permittivity of a lossy dielectric inclusion in a parallel-plane waveguide from the reflection and transmission characteristics. The approach is based on the analysis of asymptotic representations of a solution to the direct problem of diffraction of a transverse electric wave and...

متن کاملFrequency-Dependent Complex Permittivity Reconstruction of Layered Diaphragm in a Rectangular Waveguide: Comparison with Experiment
This study employs the technique developed in the earlier studies of the authors aimed at complex permittivity reconstruction of layered materials in the form of diaphragms (sections) in a single-mode waveguide of rectangular cross section from the transmission coefficient measured at different frequencies. The permittivity is assumed to be a function of frequency. We develop a numerical-analyt...
متن کاملA Volume Singular Integral Equation Technique for Reconstruction of Complex Permittivity of a Body in a Rectangular Waveguide
The theoretical study outlined in this paper is motivated by the growing interest in microwave imaging in closed microwave systems. We present an original approach to the inverse problem of reconstruction of media parameters (complex permittivity) of a body in a waveguide. The consideration is based on the use of a volume singular integral equation and its reduction to an equation which can be ...
متن کاملMeasurement of Complex Permittivity of Liquids Using Waveguide Techniques
Complex permittivity of a number of liquids and binary mixtures has been studied by measurement using the waveguide techniques at the X and Ku band. Particular pieces of WR90 and WR62 waveguides were designed for the measurement of liquid materials. The custom designed TRL calibration kits are applied for calibration of the waveguide system. The measured results of complex permittivity of liqui...
