Radio frequency interference

2008 IEEE International Symposium on Electromagnetic Compatibility, 2008
➢ Radiation from processor packages was investigated using a simplified 3D numerical model. The radiation pattern (Near field) agrees with measurement ➢ Preliminary results show that the package PDN resonance may be the major reason that P1 radiates more than P2 ...

Measurements at Radio Frequencies

Transactions of the American Institute of Electrical Engineers, 1940
IT IS interesting to recall that this art is less thana century old1 and that the early experimenters actually worked in the frequency range now called “hyper frequencies.”

A Rydberg atom-based mixer: Measuring the phase of a radio frequency wave

Applied Physics Letters, 2019
Rydberg atoms have been shown to be very useful in performing absolute measurements of the magnitude of a radio frequency (RF) field using electromagnetically induced transparency.

Ammonia Synthesis by Radio Frequency Plasma Catalysis: Revealing the Underlying Mechanisms

ACS Applied Energy Materials, 2018
Nonthermal plasma is a promising alternative for ammonia synthesis at gentle conditions. Metal meshes of Fe, Cu, Pd, Ag, and Au were employed as catalysts in radio frequency plasma for ammonia synthesis.

Photonic radio frequency phase-shift amplification by radio frequency interferometry

Optics Letters, 2015
We present a new technique for radio frequency (RF) phase-shift amplification based on RF interferometry and demonstrate it in an optical system. A striking feature of this amplifier is that the input phase noise is not amplified together with the input phase signal, so the phase sensitivity improves with higher phase amplification.

Radio-Frequency Spectroscopy

1991
Whereas the resolution in optical investigations of free atoms is limited by different broadening mechanisms in the light source and the spectral equipment, resonance methods yield a linewidth which is limited essentially only by the Heisenberg uncertainty relation.

200 GHz Maximum Oscillation Frequency in CVD Graphene Radio Frequency Transistors.

ACS Applied Materials and Interfaces, 2016
Graphene is a promising candidate in analog electronics with projected operation frequency well into the terahertz range. In contrast to the intrinsic cutoff frequency (fT) of 427 GHz, the maximum oscillation frequency (fmax) of graphene device still ...
