Fast RF-CV characterization through high-speed 1-port S-parameter measurements [PDF]

, 2010
We present a novel method to measure the capacitance-voltage relation of an electronic device. The approach is accurate, very fast, and cost-effective compared to the existing off-the-shelf solutions.

Real-Time Prediction of Rate of Penetration in S-Shape Well Profile Using Artificial Intelligence Models

Sensors, 2020
Rate of penetration (ROP) is defined as the amount of removed rock per unit area per unit time. It is affected by several factors which are inseparable.

Development and investigation of the characteristics of a volumetric resonator for an automated information and measurement system for determining the dielectric parameters of ferrites in the ultrahigh frequency range

Вестник Самарского государственного технического университета. Серия: Технические науки
The production of ultra-high-frequency ferrites is a complex, multi-stage process requiring control of materials and operating conditions at all stages. Small deviations in any process step can lead to significant changes in the dielectric parameters of ...

Fast S-Parameter TAN Model of n-Port Lumped Structures

IEEE Access, 2019
This paper deals with the fast S-parameter modeling of multi-port lumped structures. The developed model is based on unfamiliar formalism using the tensorial analysis of networks (TAN).

Three-parameter deformation of ℝ × S 3 in the Landau-Lifshitz limit

Journal of High Energy Physics, 2021
In this article we construct the effective field theory associated to the ℝ × S 3 sector of the three-parameter deformation of AdS3 × S 3 × T 4 in the Landau-Lifshitz approximation.

Moose models with vanishing $S$ parameter

, 2004
In the linear moose framework, which naturally emerges in deconstruction models, we show that there is a unique solution for the vanishing of the $S$ parameter at the lowest order in the weak interactions.

Stability Analysis and Hopf Bifurcation of a Delayed Diffusive Predator–Prey Model with a Strong Allee Effect on the Prey and the Effect of Fear on the Predator

Mathematics, 2023
In this paper, we propose a diffusive predator–prey model with a strong Allee effect and nonlocal competition in the prey and a fear effect and gestation delay in the predator.

Fully parameterized macromodeling of S-parameter data by interpolation of numerator & denominator [PDF]

, 2012
A robust approach for parametric macromodeling of tabulated frequency responses is presented. An existing technique is modified in such a way that interpolation is performed at the numerator and denominator level, rather than the transfer function level.

Complex Permittivity Measurements of Film-Type Materials: Effect of the Waveguide Flange

IEEE Access
The flexibility and thinness of most film-type materials make it difficult to use conventional measurement methods such as those in international or organizational standards to accurately measure the complex permittivity of these materials.

Uncertainties of S-Parameter Measurements in Rectangular Waveguides at PTB [PDF]

Advances in Radio Science
In this work the determination of measurement uncertainties in scattering parameter measurements for waveguide interfaces ranging from R 100 (WR 90) to R 2.6k (WR 3, WM-864) is presented.
