Non-destructive evaluation of defects in thermal barrier coating system using combined electromagnetic and thermographic signals [PDF]

Nature Communications
Thermal barrier coating system plays key role in high temperature gas turbine blades. During the manufacture and in-service processes, defects are inevitable due to the inconsistent deformation and fatigue loading. The typical defects, e.g.

Microwave Complex Permittivity of Yttria-Stabilized Zirconia

IEEE Open Journal of Instrumentation and Measurement, 2023
The complex permittivity of 8-mol yttria-stabilized zirconia (8-YSZ) in powder and sintered (i.e., solid) forms were measured from 32 to 40 GHz using a circular waveguide probe.

A Review of Chipless RFID Measurement Methods, Response Detection Approaches, and Decoding Techniques

IEEE Open Journal of Instrumentation and Measurement, 2022
Chipless RFID systems can be considered as a special case of passive RFID systems, where the tag contains no power source and no electronics. Instead, the tag’s information is stored in its structure and accessed through its electromagnetic (EM ...

Local Sensitivity Analysis and Monte Carlo Simulation to Examine the Effects of Chipless RFID Measurement Uncertainties—Part I: Misalignment-Based Uncertainty

IEEE Open Journal of Instrumentation and Measurement, 2022
Measurement and response decoding is an ongoing challenge in the chipless radio-frequency identification (RFID) field. Measurement uncertainties, including tag/reader misalignment, radar cross-section or S-parameter error, and clutter, can cause response
