Contactless Waveguide Characterization of Piezoresistive Materials for Wireless Strain Sensors
Sensors, 2022 Stretchable materials are widely used for the realization of various sensors, but their radio frequency behavior has not been fully characterized so far. Here, an innovative method is proposed for deriving the surface impedance of this kind of materials.

Reflection Coefficient Stability Criterion for Multi-Bus Multi-VSC Power Systems
IEEE Access, 2020 This paper proposes a reflection coefficient stability criterion for multi-bus power systems with multiple voltage-source converters (VSCs). In the method, VSCs are modeled as two-port networks, which are then characterized by the incident and reflected ...

Effect of Spatial Modulated Light on Position of Self-Calibration Point
IEEE Photonics Journal, 2021 In optical sensing, the differentiation between absorption and scattering poses a challenge when dealing with a physiological medium. We have shown that for extracting absorption-based parameters it is optimal to measure at the iso-path length (IPL ...

Transport of quantum noise through random media [PDF]
, 2004 We present an experimental study of the propagation of quantum noise in a multiple scattering random medium. Both static and dynamic scattering measurements are performed: the total transmission of noise is related to the mean free path for scattering ...
