Changes in a Printed Circuit Board's Absorption Cross Section Due to Proximity to Walls in a Reverberant Environment [PDF]

open access: yes, 2016
Knowledge of the Absorption Cross Section (ACS) of a Printed Circuit Board (PCB) is essential when defining an enclosure’s shielding effectiveness as it will determine how a PCB affects the internal electromagnetic (EM) field inside the enclosure.

Inverse Fourier transform technique of measuring averaged absorption cross section in the reverberation chamber and Monte Carlo study of its uncertainty [PDF]

open access: yes, 2016
The averaged absorption cross section (ACS) of a lossy object characterises its ability to capture power from diffused electromagnetic waves. The averaged ACS is very important in many EMC research areas such as indoor wireless channel modelling and ...

Estimation of Required Characteristic Modes for Stirrers in a Reverberation Chamber

open access: yesIEEE 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

Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials

open access: yesAdvanced Materials Technologies, Volume 10, Issue 11, June 5, 2025.
This work presents an dual acoustic metamaterial for rooms that achieves excellent broadband performance for both sound absorption and sound diffusion. This is done by using causality formulations linking the absorption of the passive system to its volume, yielding an optimal surface area ratio required for excellent sound absorption and while ...

Effect of power state on absorption cross section of personal computer components [PDF]

open access: yes, 2017
Knowledge of the shielding effectiveness of an enclosure is important for the electromagnetic compatibility of electronic systems. The shielding effectiveness of an enclosure depends on the absorption cross section of its contents.

Absorption cross section measurement of stacked PCBs in a reverberation chamber [PDF]

open access: yes, 2016
The Absorption Cross Section (ACS) of Printed Circuit Boards (PCBs) can be used to help determine how PCBs affect the internal electromagnetic (EM) field in a shielded enclosure and thus the enclosure shielding effectiveness.

MARS: Programmable multipurpose auto‐release system for aquatic observations

open access: yesLimnology and Oceanography: Methods, Volume 23, Issue 6, Page 376-388, June 2025.
Abstract Aquatic biodiversity assessments are often labor‐intensive due to the large size of the equipment and the complex logistics of sea vessel operations. Traditional drift and drop cameras are typically tethered to the surface, causing cable and line clutter on sea vessels.

Predicting the statistics of wave transport through chaotic cavities by the Random Coupling Model: a review and recent progress

open access: yes, 2013
In this review, a model (the Random Coupling Model) that gives a statistical description of the coupling of radiation into and out of large enclosures through localized and/or distributed channels is presented.
