Experimental Investigation of the Number of Independent Samples and the Measurement Uncertainty in a Reverberation Chamber [PDF]

, 2013
Due to the complicated and time-varying boundary conditions, reverberation chamber (RC) measurements are usually studied using statistical analysis. Hence, it is of importance to know the number of independent samples of the measurements.

Estimation of Required Characteristic Modes for Stirrers in a Reverberation Chamber

IEEE Access
This paper investigates an approach for assessing stirrer performance in a reverberation chamber (RC) using characteristic mode analysis (CMA). In the design of a reverberation chamber, evaluating stirrer performance is crucial; however, it is considered

Enclosure shielding assessment using surrogate contents fabricated from radio absorbing material [PDF]

, 2016
The electromagnetic environment inside an equipment enclosure at high frequencies is strongly dependent on the absorption of energy by the contents. This effect is neglected by current shielding measurement standards.

Frozen Differential Scattering in Reconfigurable Complex Media

Laser &Photonics Reviews, EarlyView.
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Using Akaike Information Criterion for Selecting the Field Distribution in a Reverberation Chamber [PDF]

, 2013
Previous studies on modeling the random field (amplitude) in a reverberation chamber (RC) were conducted either by fitting a given distribution to measured data or by comparing different distributions using goodness-of-fit (GOF) tests.

The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

Responsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

MXene‐Coated 3D Printed Horn Antennas for Ku Frequency Band

Advanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.
An additive manufacturing approach to 3D printing horn antennas and coating them with Ti3C2Tx MXene is proposed. Rapid fabrication of lightweight, high‐performance antennas operating in the Ku‐band (12.4–18 GHz) has been demonstrated. The MXene‐coated antennas exhibit comparable electromagnetic performance to conventional, costly aluminum ones, with ...

Exposure to 5G-NR electromagnetic fields affects larval development of Aedes aegypti mosquito

Scientific Reports
Telecommunication networks, including 5G New Radio (5G-NR), emit these fields and consequently expose many insects. To quantify the potential effect of RF-EMF exposure on insects, a study was designed examining the development of the Aedes aegypti ...
