Passivity Check of $S$-Parameter Descriptor Systems via $S$-Parameter Generalized Hamiltonian Methods [PDF]

open access: yesIEEE 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 De-Embedding Error Estimation Based on the Statistical Circuit Models of Fixtures

open access: yesIEEE transactions on electromagnetic compatibility (Print), 2020
S-parameter de-embedding methods require multiple fixtures to be identical. However, due to manufacturing variations, the fixtures are never perfectly identical, which violates the assumptions for the de-embedding algorithms and, in turn, introduces ...

S matrix for a three-parameter integrable deformation of AdS 3 × S 3 strings

open access: yesJournal of High Energy Physics, 2020
We consider the three-parameter integrable deformation of the AdS 3 × S 3 superstring background constructed in arXiv:1811.00453. Working on the string worldsheet in uniform lightcone gauge, we find the tree-level bosonic S matrix of the model and study ...

GRNN-Based Scattering Parameter Modeling Investigation for HBT at Different Temperature

open access: yesIEEE Access, 2023
In this paper, the scattering parameter (S-parameter) modeling method for heterojunction bipolar transistor (HBT) at different temperatures is investigated. S-parameters of HBT at different temperatures are randomly divided into training and testing sets,

One parameter family of S-tangent surfaces

open access: yesActa Scientiarum: Technology, 2015
In this paper, we study S-tangent surfaces according to Sabban frame in the Lorentzian Heisenberg group Heis³. We obtain differential equations about in terms of their geodesic curvatures in the Lorentzian Heisenberg group Heis³.
