چکیده
In this communication, a novel method to characterize the thermal dilatation of metals using contactless measurement frequency-dependent reflection coefficient resonator is introduced. This wireless technique allows extracting expansion material without need any calibration. Two antennas, VNA, and scatterer fabricated with under-test are required. All measurements have been achieved climatic chamber absorbers control scatterer's temperature. The measured values for coefficients in good agreement provided by manufacturer which confirmed sensibility study.

متن کاملUltra-High Accuracy Measurement of the Coefficient of Thermal Expansion for Ultra-Low Expansion Materials
Microlithographic systems rely on precision alignment and a high-level of dimensional stability to achieve required performance. In critical applications, immunity to thermally induced dimensional changes is achieved by the use of low coefficient of thermal expansion (CTE) materials such as ULE® in components such as reflective optics and machine structures. ULE® has an expansion coefficient (α...

The coefficient of thermal expansion ~CTE! of hydrogenated amorphous carbon (a-C:H) was investigated as a function of the concentration of sp hybridization. The CTE, determined using the thermally induced bending technique, depends on the concentration of sp bonded carbon, increasing to the value of graphite as the sp concentration approaches 100%. By using a combination of the thermally induce...
