Surface Acoustic Wave (SAW) Tags Structures and Models

Elektronika ir Elektrotechnika, 2005
Surface acoustic wave (SAW) tags have a perspective future. For better read range and technology improvement is reasonable to use single destination converters, working on the main frequency harmonics. In the paper provided single destination double section SAW tag model, which assessed charge distribution in electrodes type, secondary effects, loss ...

Modeling and simulation of the influence mechanism of ice accretion on SAW propagation

AIP Advances
Icing causes instantaneous attenuation of surface acoustic wave (SAW), which can be leveraged for fast and highly sensitive detection of ice accretion. However, the specific mechanism of acoustic attenuation during the icing process is unclear, leading ...

Experimental Investigation of Moisture Movement During Freeze–Thaw Cycles and Its Effect on Physical Rock Weathering in Low‐Porosity Alpine Limestone

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The progressive weakening of alpine rockwalls through subcritical cracking, driven by repeated low‐magnitude stress processes, plays a key role in alpine rock weathering. Laboratory studies using acoustic emission (AE) monitoring have shown that thermal stresses from freeze–thaw cycling induce crack propagation, with recent work highlighting ...

Identification of invisible damage in prestressed concrete bridges—A demonstrator case using coda wave interferometry

Structural Concrete, EarlyView.
Abstract During their life cycle, prestressed concrete bridges are prone to wire breaks of their tendons due to fatigue or stress corrosion cracking. However, not all structures show visible cracking on the surface, which would provide timely warning of otherwise invisible damage. Brittle failure may occur.

Toward Metabolomics Analyses With Combined Capillary Vibrating Sharp‐Edge Spray Ionization and Atmospheric Pressure Chemical Ionization

Rapid Communications in Mass Spectrometry, Volume 40, Issue 17, 15 September 2026.
ABSTRACT Rationale The varied properties of metabolomics components dictate the tools used in mass spectrometry (MS) characterization including the selection of the ionization source. However, the ionization of select compounds limits characterization efficiency.
