An Integrated Detection Circuit for Transmission Coefficients [PDF]

open access: yesIEEE Access, 2020
As the applications of radio-frequency (RF) circuits continue to prosper, scattering parameters (S-parameters) play an essential role in the verification of a variety of chips. The traditional way to measure the S-parameters of RF integrated circuits (RFICs) is by using vector network analyzers (VNA).

Transmission Eigenvalues for Operators with Constant Coefficients [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2010
In this paper we study the interior transmission problem and transmission eigenvalues for multiplicative perturbations of linear partial differential operator of order $\ge 2$ with constant real coefficients. Under suitable growth conditions on the symbol of the operator and the perturbation, we show the discreteness of the set of transmission ...

Transmission coefficients of superconducting particles

open access: yesFine Chemical Technologies, 2021
Objectives. There is no general theory of superconductivity capable of fully describing this phenomenon, which imposes its own difficulties in the search for new superconducting materials, as well as in the study of their properties. In particular, the electrodynamics of a superconducting system is unexplored.
