Physical review letters, 2010 We propose a direct test of the existence of gauge duals for nonsupersymmetric asymptotically free gauge theories developing an infrared fixed point by computing the S-parameter in the electric and dual magnetic description. In particular we show that at the lower bound of the conformal window the magnetic S-parameter, i.e.

BPNN-Based Behavioral Modeling of the S-Parameter Variation Characteristics of PAs with Frequency at Different Temperatures [PDF]
Micromachines, 2022 To address the issue of frequency nonlinearity modeling of RF PAs, which is rarely seen in the literature, a BPNN is applied to model the frequency nonlinearity of RF PAs in this paper.

ACD estimation of the S-parameter revisited [PDF]
Physics Letters B, 1997 The analytic continuation by duality (ACD) technique has been used to estimate the electroweak S parameter in technicolor models. In this letter, we investigate the reliability of this method by applying it to some toy models with known spectra. We find that in most instances the technique cannot be trusted to give a reliable result.

Improving Ultrasonic Power Transfer in Air Through Hybrid S-Parameter Modeling and High-Efficiency Compensation [PDF]
SensorsUltrasonic Power Transfer (UPT) offers several advantages over electromagnetic-based wireless power transfer (WPT), but its implementation in the air still faces significant challenges.

Passivity Check of $S$-Parameter Descriptor Systems via $S$-Parameter Generalized Hamiltonian Methods [PDF]
IEEE Transactions on Advanced Packaging, 2010 This paper extends the generalized Hamiltonian method (GHM) (Zhang , 2009; Zhang and Wong, 2010) and its half-size variant (HGHM) (Zhang and Wong, 2010) to their S -parameter counterparts (called S-GHM and S-HGHM, respectively), for testing the passivity of S -parameter descriptor-form models widely used in high-speed circuit and electromagnetic ...

S Parameter in the Holographic Walking/Conformal Technicolor [PDF]
Progress of Theoretical Physics, 2008 We explicitly calculate the $S$ parameter in entire parameter space of the holographic walking/conformal technicolor (W/C TC), based on the deformation of the holographic QCD by varying the anomalous dimension from $γ_m \simeq 0$ through $γ_m \simeq 1$ continuously.

Assessment of Measurement Uncertainty for S-Parameter Measurement Based on Covariance Matrix [PDF]
SensorsS-parameters are widely used to detail the scattering parameters of radio frequency (RF) components and microwave circuit modules. The vector network analyzer (VNA) is the most commonly used device for measuring S-parameters. Given the multiple frequency

The oblique S parameter in Higgsless electroweak models [PDF]
AIP Conference Proceedings, 2012 We present a one-loop calculation of the oblique S parameter within Higgsless models of electroweak symmetry breaking. We have used a general effective Lagrangian with at most two derivatives, implementing the chiral symmetry breaking SU(2)_L x SU(2)_R -> SU(2)_{L+R} with Goldstones, gauge bosons and one multiplet of vector and axial-vector ...
