In-situ high field strength testing using a transportable reverberation chamber [PDF]

open access: yes, 2008
A reverberation chamber can create very high fieldstrength with moderate input power. Existing chambers are making use of a paddle wheel to change the resonant modes in the chamber.

Oxygen‐Driven Structural Reorganization by Trace Water Enabling Fast Li‐Ion Transport in a Pliable Solid Electrolyte

open access: yesAdvanced Energy Materials, EarlyView.
Trace water is acting as a constructive mediator in 2LiCl–GaF3, markedly increasing ionic conductivity while reorganizing local coordination. Hydration creates localized Li+ solvation environments and partially dissociates ion pairs, enhancing Li‐ion mobility.

Unveiling the High‐Voltage Reactivity and Gas Evolution With Aluminum‐Based Chloride and Oxychloride Catholytes in Solid‐State Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
The work examines the electrochemical and interfacial behaviors of crystalline NaAlCl4 and amorphous Na–Al–oxychloride solid electrolytes with NaNi0.5Mn0.5O2 cathodes. Operando gas evolution and ToF‐SIMS analyses highlight that pure chloride solid electrolytes offer greater interfacial stability and safety compared to the oxychloride solid electrolytes

Evolution of Physical Intelligence Across Scales

open access: yesAdvanced Intelligent Discovery, EarlyView.
By following the evolution of physical intelligence across scales, this article shows how intelligence arises from materials, structures, physical interactions, and collectives. It establishes physical intelligence as the evolutionary foundation upon which embodied intelligence is built.

The effect of peripheral equipment loading on reverberation-chamber metrics [PDF]

open access: yes, 2019
Measuring wireless devices in a reverberation chamber often requires ancillary equipment to be present in the chamber. This paper illustrates the effect of their presence on metrics that are important in wireless device tests, such as chamber decay time,

Measurements of acoustics properties for level-dependent ear-muffs

open access: yesArchives of Acoustics, 2003
The aim of this paper is to present methods of acoustic measurements of level-dependent ear-muffs with an electronic sound restoration system switched off and on, according to EN 352-4.

Statistics of the electromagnetic response of a chaotic reverberation chamber

open access: yesAdvanced Electromagnetics, 2015
This article presents a study of the electromagnetic re- sponse of a chaotic reverberation chamber (RC) in the pres- ence of losses. By means of simulations and of experi- ments, the fluctuations in the maxima of the field obtained in a conventional mode-

The psychosocial toll of Dublin III on asylum seekers in the Netherlands

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract The Dublin III Regulation determines which EU Member State is responsible for examining asylum claims, but its implementation carries significant consequences for those subjected to it. This study examines how Dublin III, as implemented in the Netherlands, affects asylum seekers' psychosocial wellbeing using Silove′s Adaptation and Development

Experimental Verification of the Weibull Distribution in a Reverberation Chamber

open access: yesInternational Journal of Antennas and Propagation, 2019
A Weibull distribution has been proposed for the probability density function (PDF) of the magnitude of the E-field in a reverberation chamber (RC). However, the Weibull distribution has two parameters, and if the parameters are position sensitive, the ...

Statistical behaviour of transmit antenna orientation in a reverberation chamber

open access: yes, 2022
Reverberation chamber (RC) is one of the electromagnetic compatibility (EMC) facilities for radiated emission and radiated susceptibility test. The RC is unique because it allows many directions for illumination an object with a higher field strength ...
