The wireless identification of passive and chipless EM sensors may be based on multi-band microwave resonators for encoding data into a specific spectral signature or microwave barcode [9]-[11]. By using an Ultra-WideBand
The wireless measurement of various physical quantities from the analysis of the RADAR Cross Sections variability of passive electromagnetic sensors is presented. A millimetre-wave Frequency-Modulated Continuous-Wave RADAR is used for both remote sensing and wireless identification of sensors. Long reading ranges (up to some decameters) may be reached at the expense of poor measurement resoluti...
متن کاملSelective Pyroelectric Detection of Millimetre Waves Using Ultra-Thin Metasurface Absorbers.
Sensing infrared radiation is done inexpensively with pyroelectric detectors that generate a temporary voltage when they are heated by the incident infrared radiation. Unfortunately the performance of these detectors deteriorates for longer wavelengths, leaving the detection of, for instance, millimetre-wave radiation to expensive approaches. We propose here a simple and effective method to enh...
متن کاملDesign and fabrication of a high-Q near-field probe for subsurface crack detection
Non-destructive detection and evaluation of invisible cracks in metal structures is an important matter in several critical environments including ground transportation, air transportation and power plants. In this paper, a high-Q near-field Microwave probe is designed and fabricated using defected ground structures for surface and subsurface crack detection in metal structures. For this purpos...
متن کاملApplication of Wavelet Transform as a Signal Processing Method for Defect Detection using Lamb Waves: Experimental Verification
A Lamb wave-based crack detection method for aluminum plates health monitoring is developed in this paper. Piezoelectric disks are employed to actuate and capture the Lamb wave signals. The position of crack is assumed to be aligned with the sensor and actuator. Extraction of high quality experimental results of lamb wave propagation in a plate-like structure is considerably complicated due to...
متن کاملMicrowave Detection of Circumferential Crack in Piping System of Nuclear Power Plants
In this paper a new method of microwave nondestructive testing based on electromagnetic guided waves is applied to detect circumferential crack in the piping system of nuclear power plants. Microwaves as continues wave are generated by a network analyzer and amplitude of the reflection coefficient is measured by this network. For detection of any type of crack with any orientation in the pipe, ...
