Empirical Characterization and Modeling of the Propagation Channel Inside the VIRC

open access: yesIEEE Access
Over-the-air (OTA) testing and electromagnetic compatibility (EMC) measurements are widely performed in classical reverberation chambers. A less-known reverberation chamber, yet a considerably efficient environment for generating multipath conditions, is

Transforming Plastic Waste into Strain Sensors: Multifunctional Upcycled TPEE Elastomers with MXene Multilayer Assemblies

open access: yesAdvanced Materials Technologies, EarlyView.
A sustainable approach is reported for upcycling PET waste into thermoplastic polyester elastomer (TPEE)‐based films with advanced properties, specifically designed for applications in strain sensing, conductivity, and photothermal response. Through a layer‐by‐layer deposition technique, TPEE films are fabricated with bio‐compatible chitosan (CH) or ...

Measurement with quasi-isotropic antenna of CEM coming from multisource in a reverberation chamber and in a car

open access: yesJournal of Microwaves, Optoelectronics and Electromagnetic Applications
The concern about the health risks that wireless technology can provide has grown globally thanks to the growing use of the devices by the population, by the finding that the public exposure to EMFs from the devices can be enhanced by the reflection of ...

Thermal Noise Measurements in a Reverberation Chamber

open access: yesIEEE transactions on electromagnetic compatibility (Print), 2022
Two modelsdescribing properties of the thermal noise power emerging from an antennamounted in a reverberation chamber are described. The first compares the reverberation chamber to an over-molded cavity acting as a black-body source; the second describes

The State of High‐Resolution Imaging of the Human Inner Ear: A Look Into the Black Box

open access: yesAdvanced Science, EarlyView.
High‐resolution imaging of the cochlea is challenged by numerous unique aspects of this organ, where sensorineural cells, crucial for hearing, are too small for conventional modalities like magnetic resonance imaging and computed tomography. This article reviews current imaging techniques, emerging technologies, and innovations aimed at improving ...

Probability Distributions of Random Electromagnetic Fields in the Presence of a Semi-Infinite Isotropic Medium [PDF]

open access: yes, 2006
Using a TE/TM decomposition for an angular plane-wave spectrum of free random electromagnetic waves and matched boundary conditions, we derive the probability density function for the energy density of the vector electric field in the presence of a semi ...

Experimental validation of the diverse incident angle performance of a pulse-width-dependent antenna based on a waveform-selective metasurface in a reverberation chamber

open access: yesAIP Advances
We present experimental validation results of a pulse-width-dependent antenna based on a waveform-selective metasurface that behaves differently according to the incoming waveform, more specifically, the incoming pulse width, even at a fixed frequency ...
