Black hole jet power from impedance matching [PDF]
, 2015 Black hole jet power depends on the angular velocity of magnetic field lines, $\Omega_F$. Force-free black hole magnetospheres typically have $\Omega_F/\Omega_H \approx 0.5$, where $\Omega_H$ is the angular velocity of the horizon.

Setup for shot noise measurements in carbon nanotubes [PDF]
, 2006 We have constructed a noise measurement setup for high impedance carbon nanotube samples. Our setup, working in the frequency range of 600 - 900 MHz, takes advantage of the fact that the shot noise power is reasonably large for high impedance sources so ...

High-efficiency microwave heating method based on impedance matching technology
AIP Advances, 2019 In a microwave heating process, part of microwave power may be reflected on the air-heating sample interface due to the impedance mismatching, caused by the relative dielectric permittivity difference between the air and the heating sample.

Impedance Matching Network [PDF]
, 2022 <p> In this article, four different matching network will be introduce and their value in network will be given by hand calculating and computer analysis. In the first matching network we just use inductor. In the second matching network, we just use a simple LC matching network with up-converting to match a 1Ω to 50Ω.

Adaptive Antenna Impedance Matching Using Low-Complexity Shallow Learning Model
IEEE Access, 2023 In this paper, an automatic antenna impedance matching technique is presented for a wide range of frequency bands where a low-complexity shallow learning model adaptively determines the component values of the matching circuit on a real-time. In general,
